Firefox 4 freezes up, then crashes Windows 7 64-bit on launch
On a completely fresh system (set it up yesterday) Firefox was working last night, but when I finished installing the rest of the system this morning (graphics card, anti-virus) it stopped working. Now, when I launch it, nothing happens untill Windows goes into a BSoD.
Reinstalling doesn't work, neither does starting it in safe-mode or Windows safe-mode.
It seems obvious that Avast! is the culprit, but since it doesn't start in Windows safe-mode and my wife uses the same programs I don't think it is.
I'm stumped, any ideas?

I have this problem too in my window 7 32-bit. I am using 3.6 without any problem. Then I upgraded to 4, unfortunately it crashes every now and then. Don't know what causes the crash.
So I just uninstalled Firefox4 and reinstall my old 3.6 version.
I hope the firefox techies would resolve this problem.
A few more details:
A friend who read my Windows crash dumps suggested it might be bad memory, but memcheck turned up no problems. The freezing is every time Firefox launches, not occationally. Switching to 3.6 didn't work, nothing happens when I try launching it (it appears for a split second in task manager before disappearing again).
I have run memtest86, which returned no errors. I am running from a OCZ Agility 2. When I accessed the profile folders from WinPE the OCZ drive went offline, very similar behaviour to the situation from normal windows, but no bluescreen... The bluescreen is probably caused by the boot drive disappearing ;). I was able to move the profile folders from an Ubuntu live dvd. However back in Windows Firefox still makes windows go down.
Downgraded from FF 4.0.1 to 4.0.0 and It's fine again.
I've had the same problem on windows 7 64 bit. It also happens with the new Thunderbird. I'm gonna try to downgrade and we'll see what happens(:
I tried that and the suggestion mozilla has put out with disabling the norton add ons. Still no luck. Seriously I hate Chrome, so someone please help(:
Well, I solved the problem myself, but I figured I'd let the thread die a natural death unless someone else had something similar. In my case, it was really stupidly simple, and the answer was in my original post: I had installed the anti-virus and the graphics card, and the anti-virus wasn't the culprit.
When I installed my graphics card I also installed outdated drivers, so after updating the graphics card Firefox worked normally again.
Hope this works for someone else as well.
How do you downgrade Firefox w/o losing settings?
My GPU drivers are up to date. Hopefully the hotfix from Norton does the job. For now I get to wait):
