Create a new profile as a test to check if your current profile is causing the problems.

See "Basic Troubleshooting: Make a new profile":

• https://support.mozilla.com/kb/Basic+Troubleshooting#w_8-make-a-new-profile

There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.

If that new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.

I also can't get into the profile manager. Got this crash ID: bp-3b4e9fd0-db29-4969-8a1a-0e9852111014

Is there some debug version I can run? I'm a developer myself, so getting some debug out is not a problem.

Btw I have tried: -reinstall -disable fingerprint driver -safe mode

your crashreport say that you are using Firefox 7, please upgrade your browser to Firefox 8 and check

• getfirefox.com

windows event log says (which makes it look similar to Bug 680927):

It seems I'm not even getting new crash reports. Here's a dump from the latest windows event log: Faulting application name: firefox.exe, version: 8.0.1.4341, time stamp: 0x4ec9a124 Faulting module name: unknown, version: 0.0.0.0, time stamp: 0x00000000 Exception code: 0xc0000005 Fault offset: 0x00000400 Faulting process id: 0x20b0 Faulting application start time: 0x01ccb32f3578a94b Faulting application path: C:\Program Files\Mozilla Firefox\firefox.exe Faulting module path: unknown Report Id: 74668d43-1f22-11e1-b251-cc52af88e02f

Thanks Knorretje. It turns out I had Passlogix V-GO.

Completely useless piece of software which I don't use, so I disabled it by following MikeBy's second reply here: https://support.mozilla.com/en-US/questions/880042#answer-252425
