Firefox keeps crashing on start-up

Since Sunday evening (3-3-13) Firefox immediately crashes when I try to start: The windows that is opened just freezes and sometimes it doesn't even open at all (although the process is running). Curious thing is that when I remove Firefox and re-install it, it works completely fine UNTIL I close the browser and try to open it again. Then it's back to crashing again.

Firefox also crashes when starting it in safe mode and it even crashes if I try to make a new profile. Basically, every Firefox thing crashes. When I boot Windows in safe mode the browser runs fine again though.

No crash reports are created so I can't provide those.

I have disabled all add-ons btw but that doesn't make a difference

Re: Firefox keeps crashing on start-up

Hello, if it works in Windows Safe mode there is a problem with other software, likely security software or a system driver, that is running on your pc. Make sure that you have the latest updates of your security software.

If you like use the Autoruns utility and check which software and services gets started, but be careful if you want to disable a specific service : http://technet.microsoft.com/en-us/sysinternals/bb963902.aspx
