I have always used Firefox on my PC.
Now I am unable to open it, getting an error "couldn't load XPCOM".
I want to just uninstall it, because we use Chrome at work and I am using that now.

I can't get rid of it.
I've tried uninstalling from Control Panel and I've tried a 3rd party program.
It is not running in the background, and I tried uninstall in Safe Mode.

Windows Vista, 64-bit

See whether if you can uninstall Firefox from here (in Safe Mode preferably):

%PROGRAMFILES(x86)%\Mozilla Firefox\uninstall\helper.exe

If that doesn't work, the only choice is to delete Firefox's folders manually. ALL your personal data will be lost. Delete these:

%PROGRAMFILES(x86)%\Mozilla Firefox

Unfortunately, the registry entries won't be removed... but there's really nothing much you can do about it.
