Since yesterday my Firefox will not open anymore. It started with a problem concerning all my browsers; I could open them, click inside them, but whenever I'd start typing anything, they would freeze. I'd get a 'Not Responding' message and I'd have to close the programmes. However, a restart fixed this for Chrome and IE. Firefox got worse after that; whenever I open it now it won't even load, I immediately get a 'Not Responding' message and I'm forced to close the programme. I've tried uninstalling and reinstalling. All support articles here suggest clearing cache and all that, but I can't do anything because it just immediately freezes.
