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.
