When using Firefox my computer periodically locks up. My screen goes blank and everything is unresponsive. I have to to a hard reboot to get my computer back up. I'm using a 64 bit version of Windows 7 and I have the latest version of Firefox installed. I typically don't use any of the plug-ins.
Ever since I downloaded v12, my computer has been locking up at least twice a DAY. I have uninstalled and reinstalled everything, including Firefox itself, as well as Adobe, and all the plug-ins associated with the application. I've run Spybot, C-Cleaner, and my anti-virus to confirm that there's nothing else wrong with the computer outside Firefox. If the computer is rebooted and Firefox is not opened, the system is fine. But once Firefox has been opened - even if it survives the session and I close Firefox - the computer is about 75% likely to lock up, requiring a hard reboot. I'm running Vista Home edition (32 bit). If anyone has a clue what might help stop this - because I'm quite sure that it's not healthy for my computer to be hard rebooted twice (or more) a day - I'd love to hear it! It's getting waaaay more than annoying, enough so that I'm ready to move to another browser to stop the problem.
