i suggest to you uninstall mozilla (but firts download again the last version) take note of yours addons (to install them one more time) after you must uninstall mozilla use the program c cleaner ( its free), clean all and the register too when you finish start to open mozilla (new version) and you will see how mozilla works great another time

How do I uninstall Firefox? This is very strange because it never crashed like this before!

me too. it didn't even start. the crash reporter pops up right after i clicked FF icon.

i don't wanna uninstall. any other way ???

The only thing I've added/changed recently is the sync application. You too?
