I need to completely remove Firefox from my computer and then reload it because the current one on my computer is compromised... I don't want to lose my settings, background, and toolbars if at all possible... my computer has been having a lot of problems for a long time, finally got a hacker and viruses removed but programs and apps are still having problems and all have suggested a compromised browser along with the browser itself having issues with "stop script", "not responding", freezing, crashing, and blue screen...
