At 2243, 03/03/2012 Firefox 10 crashed. I restarted it and selected restore previoius session. It promptly crashed again, so I selected new session and it again crashed on start. I restarted my machine and tried again, but FF crashed again whetehr trying to resotre session or start new. I used IE to download Firefox Setup 10.0.2.exe and ran the install, selecting upgrade (I'm pretty sure I was already running the same version). Again, crashes on start. I tried starting in safe mode (using the shift key) but it still crashes very shortly after start, even with new session. I have submitted 15 crash reports between 2243 and 2349. I have listed the first and last in the crash ID(s) section. I'll provide all 15 if it will help. This is my first real problem with FF; there are only 9 other sumbissions in my crash id folder for the period of Oct 2010 until today. I have not uninstalled and reinstalled FF- I'm hoping to avoid that so as to not lose my settings. Appreciate any help - don't want to be stuck using IE.
