hello, please try to launch firefox in safemode by pressing the shift-key while firefox is launching: Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems while in safemode, disable hardware acceleration in the firefox menu ≡ > options > advanced > general and see if you can start the browser normally then... if so, please go to the firefox menu ≡ > help ? > troubleshooting information, copy the contents of that page and paste them here into a reply on the forum? this might give us a clue what is going on & help solve the issue for other users.

I was able to get in by safe mode. The page you wanted me to copy is very, very long. I looked at the last crash report. It was re Shockwave Flash V14.0.0 file name NPSWF32-14-0-0-179.dll. ( I have seen a message many times recently re this crashing.) Referenced Bugzilla Bug 858391 and Flash Plugin Crash in F1506898907 Abobe Flash.

I am not knowledgeable at all in trying to figure out the problem. Really want to know if I delete and then reinstall Firefox....will this fix the problem. Thanks so much for your help.

hello wilma, while in safe mode, the most important step is to disable hardware acceleration within the firefox menu ≡ > options > advanced > general. then your browser should work again when you restart it normally.

the behaviour described is not a crash per se, in this case the whole application would close and you would be presented with a crash reporter dialog that lets you submit relevant data to mozilla. your issue seems more like a bug in the program that is triggered by a certain combination of factors of your system environment, a reinstall will be unlikely to solve that at the moment.

After disabling hardware acceleration, exiting, and restarting, I was able to get in normally. Does this mean the problem is fixed permanently?

THANKS SO MUCH FOR YOUR HELP!!!!!
