Firefox will not open - disappears from Task Manager after a few seconds
Everything was working perfectly fine last night. I turn on the computer this morning, try to open firefox - nothing. I click it and there's not even an error message or anything. In the Task manager, the firefox.exe appears in the Processes tab for a couple of seconds then it just disappears. I've tried running the computer in Safe Mode to open it, still nothing. I tried the Firefox Safe Mode option, still won't open. I uninstalled, then reinstalled, that didn't help.
Any suggestions? IE works fine, but I really hate using it.

A possible cause is security software (firewall) that blocks or restricts Firefox without informing you about that, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process.

- Configure firewalls so that Firefox can access the Internet

Okay, probably a really stupid question, but how do I do that? I went into Control Panel ----> Windows Firewall but I can't find any permissions or anything.
