Firefox crashes on launch, including safe mode. Windows 7 64-bit.
Firefox crashes within 2-3 seconds of launch consistently. Safe mode does not alleviate problem. Operating system is Windows 7 64-Bit.

It looks like from what me and another volunteer think is that some binary modules are corrupt. A clean installation of Firefox would most likely fix it.
