Firefox will not open

[G-MAN2004]

When I try to open Firefox this message appears:

It's not even running though. I've tried uninstalling/deleting it but it still doesn't open.

Any ideas?

Thanks.

Have you tried restarting ?

Haha, yep. It's been doing it for days now. I've just been too lazy to ask.

It's not running in task manager. I've tried everything on the link (thanks) but unfortunately it doesn't work.

I've had to delete the profile and everything else Firefox related. I've lost my bookmarks and everything but it works now.

Thanks.
