I have been using Firefox for a long time but since last night I can't open it anymore, I just get an error report. I have tried re-installing it but same thing happens. I'm fairly sure it's not caused by spyware (adaware, spybot and spyware doctor aren't finding anything). Does anyone have any idea what I could do to fix this? Any help will be greatly appreciated, it's the only browser I like and i'm lost without it!
