I'm having a problem sort of like the one above except without the blue screen of death. Whenever I click on Firefox, my computer will restart itself. I've tried uninstalling, by deleting from the C drive because I couldn't go through the control panel, and it still wouldn't work. I've even tried renaming firefox.exe to firefox3.exe and nothing is working. I would really love to figure this out because I cannot stand Internet Explorer. == This happened == Every time Firefox opened == Today == == User Agent == Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.0.3705; .NET CLR 1.1.4322; Media Center PC 4.0; .NET CLR 2.0.50727; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729; InfoPath.2)
