Firefox and gmail not happy

Firefox and gmail not happy
Originally uploaded by roupen

I been using my MacBook Pro happily for the last few months including Firefox 2.0 and Gmail. A couple of days ago, gmail stopped working with Firefox on my machine.

I tried clearing cookies and even reinstalled firefox but the problem wont go away. So for now, I am using Safari to read my gmail, which is not bad but its no firefox :(

Update: I upgraded to FF3 Beta and the problem went away (thanks to Noam for the suggestion). I lost a few plugins along the way that weren't compatible with FF3 but oh well.
