Firefox Aurora and its New Multi-channel Approach

With its 5.0 Beta, Firefox has debuted a new feature designed to speed up its own development to counter Google Chrome's rapid release schedule. With it's new Aurora release Firefox allows users to easily switch between three different channels: Development which is the normal version of the software, Beta which includes new features which are still being tested; and Aurora which is the latest nightly build of Firefox which can be expected to be unstable but also full of interesting new features.

It's all credibly slick and cool. Just select About Firefox in the Help Menu which tells you your channel and click Change to select a new channel. You select your new channel and click on Apply and Update and Firefox installs a new version of itself and restarts.
But I have to wonder if this is the right approach for Firefox. As slick as Firefox's channel switcher is, I prefer Chrome's approach of having separate installs of the browser for different channels. With Chrome's Canary Build, you can have your cake and eat it too. One safe, always up to date browser and another separate browser with cutting edge, experimental technology which will occasionally crash. And one can have dozens of pages open in tabs and another can open to just one or to your start page.

Aurora on the by contrast feels like an all or nothing proposition. You can switch between channels easily within one install of the browser but what happens if the latest nightly Aurora build is unstable? Will there be a way to switch to a more stable channel without bringing up the About Firefox box? I hope so.

And I think that Firefox with its more powerful extensions can benefit even more by having two separate browser installations. It is fairly common for early Betas of Firefox to be incompatible with many extensions. Having a "stable" installation of Firefox with all your favorite extensions and a second "experimental" installation which runs alongside it would probably be something that most Firefox users would enjoy.

While I realize that I could probably set this up myself using Firefox's Profile Manager, that tool is on its way out. And in any case it's probably overkill for most users. It would be much easier to have a check box that says "Maintain Separate Aurora Installation" or something like that in the About Firefox box.

Mozilla Plugin Check Runs on Any Browser

I no longer use Firefox very much. But it doesn't seem that Mozilla holds a grudge. Mozilla's new Plugin Check will check your browser for outdated plugins allowing you to head off potential security threats even if you are running on a different browser. Mozilla, a class act in a world of squabbling children.

Thanks to security guru and all around paranoid freak Steve Gibson for the tip.

Firefox Gets Proactive

I don't use Firefox as much as I used to. Chrome is just so much faster that I almost invariably turn to it first. But Firefox's rich collection of add-ons is so useful that when I have time and feel like some random web surfing, I'll usually fire up both Firefox and Chrome and use them side by side.

Tonight when I fired up Firefox, I was confronted by this dialog box. A bit aggressive no? Actually no. It turns out that Microsoft's Firefox add-ons expose Firefox users to malware attacks. I'd noticed this little piece of news this morning and by nightfall when I fired up Firefox, it was already uninstalling the Microsoft add-ons. That's a pretty fast turn around time for cleaning up a problem which was only recently discovered.

Now if only Firefox could identify the add-ons that are slowing it down....

Mozilla Fights XSS With CSP

Mozilla FirefoxImage via Wikipedia

H-online reports that Mozilla is implementing a new Content Security Policy (CSP) to guard Firefox against cross-site scripting attacks (PDF link). Cross-site scripting attacks, also known as XSS attacks are a huge problem for today's web users. Basically XSS attacks take advantage of the fact that today's websites draw content from many different servers. You may be on one website but that website is displaying ads which run on Javascript code from an ad server run by another company. And that cute little widget that shows the time? It might also be running on code from yet another server owned by yet another company. And finally those embedded videos we love to watch on the web are all running with code from Youtube or some other large video website. Worse yet, each of those third-party servers may also be running third-party code themselves.

It all starts to sound like an AIDS awareness commercial from the '90s—when you browse on one website's server, you're browsing on every server that has been in contact with. And indeed is the result. A hacker can hack one website and spray malicious code all over the Internet, compromising millions of PCs with one attack.

While Firefox's NoScript extension includes protection against XSS attacks, it has plenty of problems of its own. For one thing, it has trouble telling bad third-party Javascript from good. Every time I click on the New Post link on my own blog, NoScript asks me to confirm because it thinks that it might be an XSS attack. Furthermore, the author of NoScript has been accused of whitelisting ad servers which place ads on the NoScript website and breaking extensions which try to block them anyway. While the author of NoScript has apologized for this behavior, it points to a potential problem with attempts to fight XSS attacks.

Mozilla's new policy also involves whitelisting known safe websites and probably holds the same potential for conflict of interest. But with the web becoming more interconnected all the time and with the rise of social networking, servers are swapping code all the time now and a system like the one which Mozilla is planning to implement will be necessary to stop malicious hackers using XSS to attack PCs.

Too Many People Want a Piece of Firefox These Days

Boing Boing Gadgets links to a Washingpost blog which complains about Microsoft quietly installing a Firefox extension without permission. This isn't the first time that this has happened. While I like AVG Antivirus, they have been installing their own Firefox extension for quite some time. As with Microsoft, they do this without permission, probably on the idea that they are doing it for the user's own good. But this is a troubling trend. One of the reasons that I use Firefox in the first place—indeed the reason most people probably use Firefox—is because of the degree of customizability and control that is allows. When companies decide that they can install extensions on their users computers willy-nilly, that is a bad thing. They are essentially telling their users, "We know better what's good for you." It erodes trust and quite frankly I'm not even sure that it is legal. Firefox afterall is made by an independent company, they are not owned by Microsoft or by AVG Technologies. So my question is, aren't these companies acting like virus writers when they do this and potentially opening themselves up to a lawsuit? If so, it would probably serve them right.

New Extension Puts Wolfram Alpha's Peanut Butter in Google's Chocolate

Lifehacker links to an experimental Firefox extension which inserts answers from Wolfram Alpha into your Google searches. While Wolfram Alpha hasn't exactly set the Internet on fire, it does provide an interesting results when your questions have a mathematical slant. Because of this, Wolfram Alpha is less an alternative to an Internet search engine and more of a complement. That's the beauty of this extension. This add-on makes the Google page a bit too wide for my netbook's small screen but it should look nice on PCs with higher resolution screens. It should make a good addition to your search arsenal.

Google Chrome Hits Version 2.0, Sweet Spot

Engadget reports that Google's Chrome browser has hit version 2.0 and gives an overview of the new features. They seem especially excited by Chrome's new ability to allow users to remove embarrassing websites from the New Tab page. This doesn't seem like such a big deal to me—maybe I have no sense of shame.

I'm more excited by the new Full Screen mode. A lot of people think that Chrome with its speed and compact user interface is ideal for netbooks. I've always prefered Firefox on my netbook because of its full screen modes which hides the browser UI altogether, showing you just the web page. Chrome's implentation of Full Screen mode is not perfect. On Firefox I can hit the <ctrl>+l key to bring up Firefox's navigation bar to type URLs, search, and access the navigation buttons. Under Chrome however <ctrl>+l doesn't work in full screen mode. While this is disappointing, Chrome does still show the URLs of links when you move your mouse over them in full screen. Firefox on the other hand does not show URLs in full screen mode. I consider this to be an equitable trade.

Finally, Chrome's speed—it launches instantaneously on my Acer netbook—continues to trump Firefox by a wide margin. While I still prefer Firefox on my bigger, faster, not quite so mobile computers for it's tremendous variety of extensions, Chrome has hit the sweet spot for me in terms of usability and speed. It has earned a place as the default browser on my netbook.

Useful Extensions for Bloggers

CNET has a list of Firefox extensions for blogging. I'm not sure I agree with every extension in their list. I'm not even done reading their list. This post is mostly an excuse for playing around with Scribefire, a blog editor from their list which looks pretty promising. I've never been very happy with the way that Blogger's editor handles images. Scribefire does a better job with images and is always available in Firefox. It looks like a keeper.

So We Meet Again Yahoo!

I like to play around with different browsers. Yahoo! Mail doesn't like that. Currently I'm playing around with the new Firefox 3.5 Beta, which for some reason was named "Shiretoko" by Mozilla, when I try to read my email. And Yahoo! Mail blocks me. This isn't the first time something like this has happened. Yahoo! Mail lets certain versions of Opera log on and then sends them into a constant redirect loop when you try to access your inbox. Yahoo! Mail also complains that the 1024x600 resolution on my Acer netbook is too low.

Ironically enough, the error screen that Yahoo! Mail throws up at me lists the browsers that it supports and one of them is Firefox 2.0.0.1 or higher. Guess what Yahoo, Shiretoko is Firefox 3.5. That makes it Firefox 2.0.0.1 or higher. Your own splash screen is locking me out of Yahoo! Mail even though I'm using a browser which technically is on your list of supported browsers. Another irony? Chrome which is not in Yahoo's list works just fine with Yahoo Mail!

Granted, Yahoo! Mail does let you go to its "classic" mail page but it's nowhere near as nice as the one that they are locking down so zealously. I have been using Shiretoko on a spare laptop for about a week and I haven't had a single crash. Google applications like GMail and Google Reader work just fine with it and I suspect that Yahoo! Mail would work just fine with it too. Yahoo! needs to get its act together or it will continue to fall behind Google in terms of web app functionality.

Tree Style Tab

Steve Gibson has been promoting some of his favorite software and utilities on his podcast and he's just uncovered a really nice one. Tree Style Tab is a new Firefox extension which allows you to change the position of the tab bar and customize it in various ways. It also makes you tabs hierarchical, when you open a links from one page in new tabs, their tabs are displayed under the original page's tab in a little tree-like structure (hence the name Tree Style Tab). This is great for organizing your open web pages. It also adds some nice features to your right-click menu like the ability to highlight several and open them all at the same time which is good for viewing image galleries or for those annoying websites break up their article pages into six or more parts to serve up more ads make them more "readable."

Another nice feature of Tree Style Tab is that it allows you take advantage of the recent trend of "wide screen" displays on laptop screens and desktop monitors. By moving the tab bar to the sides, this extension reclaims vertical space on your screen and replaces it with horizontal space which is more plentiful on most people's screens these days. This is especially true with netbooks which usually have 1024x600 screens. Finally, Tree Style Tab can be set to automatically shrink or even hide the tab bar which reclaims even more space on your screen.

Overall, Tree Style Tab is one of the best Firefox add-ons I've seen.

Update: After a couple days using Tree Style Tab, I've found that while it's a bit rough around the edges, it fits very nicely into my browsing style and really complements the way I use Firefox. For example, I use Google Reader to read blogs and it has a rather convenient "Popout" feature which allows me to open embedded videos in their own window. While this is a nice feature, Tree Style Tab can also force this new window to open as a tab which expands to the size of my existing browser window. This is good as it allows almost full screen video for older computers with flaky video drivers which sometimes gag on full-screen video. (I have an older laptop which resembles that remark. Tree Style Tab can also this for almost any kind of pop up window and I tend to find pop up tabs preferable to pop up windows.

Recovery.gov—Access Problems For The Government's New Website?

The Obama administration has finally pushed its stimulus bill through Congress and has a website for it up and running. Hooray for government transparency and change you can believe in. I was pretty eager to read the bill. Actually, I probably would have just skimmed it for a few minutes and gotten bored the way I did with the House version of the bill. But I was definitely interested in looking at it if for no reason than because it was available online. While Congress has been making the text of bills available in excruciating detail for years, as far as I know this was the first time that the president went to such pains to actually publicize and build websites for a single law. The website was actually live (empty but live) for at least a week before the stimulus bill passed.

So I eagerly went to the website today and was excited to see a polished, professional, and good looking website along with a link to full text of the stimulus bill. Awesome! Then I actually clicked on the link. Nothing. Apparently, JavaScript coders are also getting a stimulus package. I use NoScript to disable scripting on websites by default in Firefox. Most websites work just fine with Javascript turned off and given how common it is these days for malicious websites to download malware onto your computer, it just makes sense for me. But I guess I can trust the government right? It's not like a politician has ever lied to me.

So I enabled JavaScript for recovery.gov and it popped up a message telling me that I was leaving the recovery.gov server displaying the full text of the link which it is sending me to. Is this really necessary? After all, the full text of any link is displayed on a browser's status bar anyway—or at least it would be if somebody hadn't decided to hide the link behind a JavaScript pop up. Still I clicked through and was taken to a the white house website where the bill conveniently divided into five parts and available in available in either PDF or ASCII formats. Excellent! Then I actually clicked on something. Another pop up. So I enable JavaScript for whitehouse.gov and click again and nothing. Aaargh! So I try one more time. Taking note of URL and enable JavaScript gpo.gov (the Government Printing Office?) and click again and nothing.

I tried to access the website again with Google Chrome and Internet Explorer. I used a brand new computer where IE had JavaScript turned on and Chrome always has JavaScript enabled but I still got the same results. Maybe the government's servers are just overwhelmed by people trying to look at the stimulus bill but if that's not the case....Between these three browsers, I probably have at least 95% of all Internet users covered and I'm a bit worried. Sure, the Bush administration screwed up Afghanistan, Iraq, and Hurricane Katrina but I've just received some very disturbing evidence that the Obama administration can't even get a simple website right.

I really hope I missed something....

Update: Checking in on the website again, it looks like they changed things around a bit. You can now download the full stimulus bill, as signed by the president, in PDF format and actually looks pretty good. Yet another document for me to download and not read. You still have to go through the annoying pop ups but at least you can download it and look at it now. My faith in democracy is restored....

Firefox Speed Tweaks

I've always been skeptical of tips for speeding up your software. So when The Boy Genius Report put out this set of set of tips for speeding up Firefox, I wasn't expecting much. Still I did try them and was pleasantly surprised to see that Firefox did perform a little better on my two laptops. As with all such tips, they require you to mess with files that are best left alone, in this case, Firefox's about:config settings. Anyway, the tips worked for me and if you know what you're doing, they are worth trying.

Chrome: Is This Your Father's Web Browser?

A couple of months ago I set up a computer for an older couple who had never used a computer before. It was an old laptop with busted hinge but it was in otherwise good condition and it was an easy matter of setting it up with an external monitor and wireless keyboard and mouse. Neither of them knew much about computers and they just wanted it for e-mail and web browsing—the same as most computer users these days.

When it came time to choose a web browser for the computer I wanted to steer them away from Internet Explorer. Besides being slow and bloated, IE is a magnet for hackers if for no other reason than the fact that it is installed on the vast majority of computers. So I installed Opera on the computer.

It seemed like a good choice at the time, Opera is small and fast—perfect for an old computer with only 512MB of RAM. Unfortunately, Yahoo! Mail didn't cooperate. Several days after setting up the computer, I began receiving calls about the a problem between Yahoo Mail and Opera. For some reason it kept redirecting Opera from its Inbox to the log-on page. I never figured out exactly why this was happening. So I installed Chrome—Google's then new browser—on the computer and the older couple has been happily using it for e-mail and web browsing ever since.

Chrome hasn't made much noise since the week when it was launched. A lot of geeks (myself included) downloaded it, complained about a lack of features and possible privacy problems, and quickly went back to Firefox. But from my perspective setting up computers for people—many of them older—who really know nothing about computers and don't care about cookie handling or security.

For these people, Chrome's shortcomings suddenly turn into strengths. Chrome was designed from the ground up to run javascript so temperamental web applications like Yahoo! Mail are more likely to run properly on it. Chrome runs in the background quietly updating itself through Google's Updater application even when it is supposed to be "closed." While more tech-savvy and paranoid people see this as a potential privacy risk, for people who neither know nor care about security or privacy issues, this is an invaluable feature since their web browser always has the latest updates and patches. While there is no way to control how javascript and cookies behave on a site by site basis, people who lack computer savvy won't know how to use these features anyway, so for them relying on Google to handle these potential threats makes sense. It all comes down to how much you trust Google—maybe you and I don't always trust Google but most people don't care one way of they other. For them Google's web browser is just another program that they run on their computer.

So for confused newbies, Chrome's lack of features and minimalist interface are an advantage. Ironically enough, Chrome's name comes from the term used by web developers for the buttons, menus, and other widgets that constitute the browser's interface. But Chrome has very little "chrome" compared to other web browsers; just front, back, and reload buttons, a combination address/search bar, and a couple of hidden menus which are easy to ignore. It even tucks its tabs into its title bar which further reduces clutter. And while Google has talked about producing add-ons for Chrome, there are currently none available. There are no toolbars or extensions for Chrome. But then again, too many extensions can slow Firefox down and toolbars are frequently more trouble than they are worth for Internet Explorer users.

So if you are a tech-savvy nerd who has been wondering what Google was thinking when they put out Chrome, maybe they were thinking about your mom and dad.

Googling Usenet

This is the sort of post which I must admit is basically just something I'm writing down so I won't forget about it. It's so nice that blogging allows me to treat the Internet as my own personal napkin.

If there is one program that I use more than any other on my computer, it's Agent. Well, I probably use a web browser, any web browser more than anything else just like everyone else. But after a web browser, I use Agent for both e-mail and for reading Usenet newsgroups. Now Agent is a pretty complex program and it has many little tricks which many people never use because they don't realize that it can do them.

One such trick is the ability to launch your web browser and retrieve a Usenet post from Google's Usenet archive. This can be useful for older topics where you want to see the whole discussion as it happened.

Setting it up is a five step process:

  1. Under the Tools | Options menu item choose URL and MIME Settings | URL Types and select news:Usenet News as your URL type.

  2. Check the following items:

    • Enable highlighting and launching

    • Remove URL prefix when launching

    • Use custom settings (below)

  3. Click Browse and point Agent to your web browser. Not every web browser works nicely with Agent to launch itself and go exactly where Agent tells it to go. Firefox works perfectly, Chrome does not. I haven't tried this trick with recent versions of Opera or Internet Explorer but based on previous experience, I would expect them to work.
  4. Check Use DDE. Use the message, http://groups.google.com/groups?selm="%1"
  5. Fill in the other DDE settings:

    • Application: Firefox (or whatever the name of the browser happens to be)

    • Topic: WWW_OpenURL

    • Method: Request

From here on, every time you double-click on the Message-ID of a Usenet post in Agent, Firefox will open a Google search for that message and go directly to it.

This kind of Google integration has been available in Agent for years and it's a good thing because Google's own Usenet newsreader is pretty bad as is its search function. Luckily, there are a number of tricks which can be used for searching Google for old Usenet topics. One of the nicest, most overlooked features of Firefox is its Keywords feature which allows you to save a custom search template and then invoke it directly from Firefox's address bar. I have a number of keyword searches for Google's newsgroup archive.

Both of the searches below can be bookmarked and used to search for a specific Message-ID. Basically, they run the above trick I use with Agent directly from Firefox's address bar.
  • http://groups.google.com/groups?selm=%s
  • http://groups.google.com/groups?as_umsgid=%s
The following search is a little more practical:
  • http://groups.google.com/groups/search?safe=off&btnG=Search&sitesearch=groups.google.com&q=%s
It searches Google's Usenet archive for any term just like a search from Google's search box. Adding the following term &as_drrb=b to that causes a snazzy set of drop down boxes to appear which allow you to narrow your search to a specific set of dates
  • http://groups.google.com/groups/search?safe=off&btnG=Search&sitesearch=groups.google.com&q=%s&as_drrb=b
Google's newsgroup URL can be customized with a wide variety of terms for saving a custom search. A full list of these terms is here.

The Acer Aspire One—Small is the New Black

I have been using the Acer Aspire One for about a week. It is one those "netbooks" that are so hip these days with the techie set. Although netbooks themselves as are a new category, the concept of a tiny notebook computer isn't that new. Sony, Panasonic, and Toshiba were all making tiny laptops for sale ten years ago. But usually these little notebooks would cost upwards of $2500 and were for the most part only available in Japan.

Originally uploaded to Wikipedia by Rico Shen http://en.wikipedia.org/wiki/User:BrockF5

But things have changed recently. As computer hardware prices have fallen and the Linux operating system has improved to the point where it can be seen as a viable alternative to Windows, it has become possible to build a really small and really cheap laptop computer. My Acer Aspire One cost me $399.


A Little History


The netbook trend has been building for about a year and a half. It sort of started when Palm, looking to revitalize its line of smartphones, announced the Foleo, a simple Linux-based laptop which was meant to be a large keyboard and screen for its Treo smartphones. Palm is primarily a cell phone and PDA maker not a computer company—and it showed with the Foleo. Equipped with wi-fi and a lightweight Linux operating system, the Foleo was capable of being a useful computer in its own right but Palm had primarily meant for it to be an accessory and marketed it as such. Because of this, the Foleo was woefully underpowered and had very little storage of its own. It was also very expensive for a phone accessory—$600, about the same price as a big clunky laptop. While its small size (which it achieved despite having a keyboard and screen which were larger and more useful than what has become the standard on netbooks) was attractive, the Foleo lacked the functionality to justify its price and Palm pulled the plug on it days before it became available for sale. I personally suspect that if Palm had tried to sell the Foleo at half the price they originally intended (in other words for $300 instead of $600), it would have been reasonably successful.

After Palm's embarrassing face plant, Asus came out with a little notebook called the EeePC. Running a lightweight version of Linux and powered by an Intel Celeron processor with a tiny screen and keyboard, the original family of EeePCs cost just $300-$500 and they were a rip-roaring success selling 355,000 units in six months. This just opened up the floodgates with competitors coming from MSI, Acer, Dell, HP, and others.

And that brings us to the Acer Aspire One which I am using now. Over time, netbooks have gravitated to a common set of specs and the Acer Aspire One is no different. It has an Atom processor which is Intel's new mobile friendly chip which has become almost ubiquitous in netbooks. It has a small but above average for netbooks 8.9 inch, 1024x600 pixel screen and a fairly small but usable keyboard—you won't be composing any novels on this keyboard but it's fine for e-mail. What separates this particular version of the Acer Aspire One from other netbooks is its 1 GB of memory and 160 GB hard drive. This is enough storage space to comfortably run Windows XP instead of the sometimes quirky Linux distributions which other netbooks use. As a result, my Acer Aspire One feels more like a normal laptop than like a "netbook."


Size Versus Speed


Without a doubt this notebook's number one feature is its small size and weight. At only about 2.5 pounds, lifting and carrying it is effortless. Here are some pictures of my 8.9" Acer Aspire One together with a 15.4" HP Pavilion dv6000 notebook and a Palm Treo 680 smartphone for comparison.








The small size of this notebook mitigates a lot of its shortcomings. I've heard people complain about the heat produced by the Acer Aspire One but I've never had a problem with it in part because it's too small to cover my entire lap. I can just prop it up on one knee for hours and barely feel any heat. This is in start contrast to my larger HP laptop which runs at least as hot, if not hotter, than my Acer netbook and because of its heat and weight quickly becomes uncomfortable in my lap. While in its default configuration Windows XP runs a bit slowly on the One, turning off its visual styles and other eye causes it to speed up considerably. (I never cease to be amazed at how much useless, performance-choking crap Microsoft adds to its operating systems.) Turning off Windows XP's visual styles also allows you to make better use of the One's small screen as XP's default styles tend to take up a lot of room on your screen.

The One also has some other useful little tricks. Intel's underpowered but useful graphics hardware comes configured with keyboard shortcuts which allow you to rotate the screen. Normally this would be a useless little trick but on the One, the screen rotation allows you to comfortably read long web pages and documents like a hard cover book. Unfortunately, when you rotate the screen, the keyboard and mouse axes remain the same which makes anything other than scrolling text awkward.

Despite all these nice little tweaks, the One still feels a little slower than a typical full sized laptop. Note that by full sized laptop, I'm referring to my two beefy HP laptops which run on dual cores and have 2 and 3 GB of ram respectively. So the One is about as fast a single core laptop with 1 GB of ram. Having said that, web browsing does "feel" a little slower on the One. I'm not sure exactly why that is, maybe its the Atom processor or maybe it's the wi-fi chipset. Or maybe it's a problem with Windows XP.

When I installed Ubuntu on the One, it detected two processors. Since most personal computers have only one processor this is usually a sign that you have a dual core processor or a processor with hyperthreading. In fact, it does appear that the Atom processor is hyperthreaded. But does Windows XP handle the Atom processor's hyperthreading? I'm not particularly knowledgeable on the issue but if I'm not mistaken, Intel abandoned its hyperthreading technology in its desktop processors in part because Windows didn't handle it well. If this is the case—and I don't really know enough about the issue to say that it is—then it might be the part of the problem. (If someone actually reads this blog and does know about this issue, I'd appreciate an e-mail on the subject.)


Software


Like most Windows laptops the One comes with a lot of crappy third party software although it comes with less than what is preloaded on HP laptops. In any case, it's nice to have PC Decrapifier around to get rid of the cruft. (Why did Acer include a copy of InterVideo WinDVD on a laptop with no DVD drive?) The idea behind netbooks is that they are lightweight both in terms of size and software and rely on Internet-based "Web 2.0" "cloud computing" to get work done. I am actually finding that I use much the same software that I would use on a normal PC. In fact at least one Web 2.0 application, Yahoo Mail actually complains that my One's screen resolution is too low even though I think that it looks just fine. Another Web 2.0 application, Google Groups gives you a full, unfiltered view of Usenet which is a little like giving you unfiltered sewer water to drink. Sorry cloud, I think I'll stick to the same e-mail and Usenet application that I've been using for over a decade thank you very much.

I was expecting that Google's Chrome browser with its minimalist interface would be ideal for a netbook. In fact I've found that good old Firefox when used in full screen mode is the best choice for me when browsing the Internet. This is great for me since I can use Foxmarks to synchronize my bookmarks between the One and my home computer which is just a really big laptop.

Beyond that, I use the One very much the same way that I would use a normal laptop. I use Firefox to surf the web, Agent for e-mail and newsgroups, GOM Player to watch video, TightVNC to log into my other computers, and Synergy to seamlessly share my mouse with my bigger computers.


Final Notes


I've only been using my Acer Aspire One for about a week but I'm already very comfortable with this little notebook. It has a glossy dark blue finish which looks great when you take it out of the box but which is also a magnet for fingerprints. It has a six cell battery which delivers about five hours of battery life. This changes the way I use my laptop. I don't worry much about battery anymore. I keep it next to my bedside for use on sleepless nights and lazy weekend mornings. It slips easily into my backpack when my older HP laptop needed some elbow grease to fit. I can take it anywhere that I expect to be able to find available wi-fi access.

This computer certainly isn't perfect. It's a little slower than what I'm used to. The touchpad has awkwardly placed buttons and is bad even by touchpad standards. The keyboard is usable but can't be recommended for long typing sessions (I'm typing this review on my big HP laptop). I've seen netbooks positioned as computers for younger people—college students, teenagers, even children. Well, with their smaller hands and sharp eyes, younger people will almost certainly be less bothered by the shortcomings of netbooks than older people.

But the bottom line is that its small size and long battery life give this computer a degree of freedom that bigger laptops can only aspire to. So as one of the first netbooks that seems to really hit the sweetspot in terms of usability for me, the Acer Aspire One is aptly named.

A Conflict Between Google Reader and Firefox?

So I fire up Firefox to read my blogs and what happens? Google Reader comes up as a blank page. I'm not sure exactly why this is the case but I do know that Chrome and Firefox 3.1, Beta 1 are not affected by this problem. Just Firefox 3. This is disappointing as many of my Firefox extensions still haven't been updated to work with the new Firefox Beta.

It's weird and disappointing but on the bright side, the new Firefox Beta is very nice—fast and stable.

Updated: In the end, I just cleared my private data and Google Reader came back. I must have had a corrupted cookie or something.

Firefox Extensions: An Embarrassment of Riches

One of the great things about the Firefox web browser is the rich mosaic of extensions which are available for it. I recently excitedly installed an extension called Hyperwords which promises to pop up a wealth of references from any word which you highlight. It looked awesome but once I restarted Firefox and had a chance to play with it, I realized that I already have several extensions which already do much the same thing. CoolPreviews does the same thing on a smaller scale—it only pops up results from Google, Google Images, The Free Dictionary, and Wikipedia while the list of references is Hyperwords pops up is too long for me to list. But CoolPreviews also pops up a minimalist window on top of my current one with a preview of any url without opening seperate page. This is a huge time saver for me which allows me to go through web pages more quickly but it's still a duplication of functionality.

And it's not the only one. Ubiquity is also an extension which I installed enthusiastically and it too replicates a lot of the functionality of Hyperwords. But it is also one of the most ambitious extensions ever created for Firefox. Essentially a command line for the web, Ubiquity can bring up everything from maps to the weather and email, twitter, slice, and dice them in many different ways. It's tremendously fun to play with and useful and it promises to grow more sophisticated as it continues to develop.

But in the meantime, I have a growing list of extensions (twenty four in all) and Firefox no longer loads instantaneously as it did when I first installed it. In fact, it actually takes about thirty seconds to start which doesn't seem like a lot but it means that Chrome, which is Google's web browser, loads instantaneously but it lacks the powerful extensions to which I've become accustomed to on Firefox. It's an interesting conumdrum, speed versus power. It's compelling enough that I often run Firefox and Chrome side by side. But that's life on the modern Internet I guess, tons and tons of information and tons and tons of ways to use it and manipulate.

Is AVG Bad For Websites?

A new website called AVG Watch claims that a component in AVG's antivirus product can overwhelm web servers by hitting them hard and downloading pages in an attempt to determine if they are hosting malware that can infect your computer. Another website complains that this component also hurts websites financially by skewing their traffic statistics which affects their ad revenue.

The component is called LinkScanner:
"LinkScanner works with both Internet Explorer and Firefox, and consists of two features, AVG Active Surf-Shield and AVG Search-Shield. AVG Active Surf-Shield prevents you from accidentally becoming infected by drive-by downloads and other exploits, ensuring the web pages you visit are safe at the only time that really matters - when you are about to click the link. AVG Search-Shield works with Google, Yahoo and MSN search engines to deliver a real-time safety verdict on all search results, including search ads, displaying an icon to show the safety rating for each site."
That's a direct quote from the documentation of AVG Anti-Virus Free 8.0 describing LinkScanner.

AVG Watch seems pretty steamed about the practice, comparing comparing it to a Denial of Service Attack. They claim that according to their own tests LinkScanner will download a page it encounters during a Google search hundreds of times more than necessary, leading to a lot of stress on webs servers as the number of people using the latest version of AVG Anti-Virus grows.

This seems like a worrisome possibility for me since I've always sworn by AVG for protecting my computers from viruses and other malware. Recently, AVG has been giving me problems with false positives and now this....

There is one ironic post-script to this episode. I have been using Firefox 3 as my main browser since its second Beta version and right now AVG Safe Search, which presumeably allows AVG to run LinkScanner within Firefox, is not compatible with the latest version of my favorite browser. So it seems that none of this applies to me right now. I'm neither "protected" from accidentally clicking on evil websites and I'm not inadvertantly "attacking" good websites either. Still, it's an interesting issue.
