Firefox upgraded itself to 3.6.10 sometime last Friday, I believe, and every since I cannot get into gmail, and it freezes often. When I try to log into gmail it will crash immediately. Sometimes if I click "sign in" rather than hitting "enter" it will load, but will lock up or crash within minutes or seconds. It also will lock up if I have more than three or four tabs open, often when loading a video, and crashed while loading Nexis, which I use often for work to do research.

I have disabled add-ons, disabled extensions, run in safe mode, uninstalled and reinstalled, rebooted, downgraded, re-upgraded. Nothing has worked.
