This morning, Firefox had updates for version 3.6.6 and I did this and now gmail is not working. The page loads and I can see my mail, but I cannot open any of the messages or compose a message and I cannot even see the people on the chat feature (I think this feature didn't even load). Since I can use gmail fine on internet explorer and have checked with other people who say there is nothing wrong with gmail, I am assuming it is a problem with the updates to firefox. My yahoo account works in firefox, so I will give you that email to reply to me.

I am experiencing the same problem with my gmail accounts as well. I also do not think it is the gmail site, since I can access my accounts on my iPhone and on my wife's computer (she currently is using Firefox 3.5.5 as her browser).
What the heck is going on? I can access it in i.e. or in the HTML version, but nothing else will work.
My problem also started last night. FF 3.6.6. I disabled all add ons, cleared cache and cookies, and gmail just hands on loading and hogs all the system resources.
I went to Tools-->Clear recent history, and cleared everything except site preferences. gmail works fine now.
I have same issue gmail just goes in to load cycle when you try to open an email. I tried clearing history had no affect. I wish Firefox would stop with the updates seems like every other day there is something that needs updating. unfortunately I have to use it for a VPN connection to work
Inbox hangs, cannot open any mail. This is DEFINITELY a FIREFOX 3.6.6 PROBLEM!!!!! I ALSO read on a forum a few days ago that FIREFOX 3.6.6. is NOT entirely SECURE...and 2 days later I got a virus which destroyed my host processing!!!! FIREFOX 3.6.6. SUCKS!!!!!!!!!!!!!!!!!!!!!!!!
