You may want to disable update checking on Firefox, that might be causing your computer to lock up. Try these steps:
' then 'Options
Click on the 'Advanced
' button with the picture of the cog and click on the 'Update
Uncheck the 'Firefox
' and 'Search Engine
' boxes and press 'OK
If that still does not work, try running Firefox in Safe Mode (no, not your computer's safe mode, Firefox's Safe Mode). You can probably find the shourtcut in your Start Menu. If lockups stop occuring, there might be a plugin or addon which might be the source of the problem because in Safe Mode, all Firefox themes and extensions are disabled. To resolve the problem if extensions are the issue, update all extensions to the latest version. Any updates available might have some bugfixes. If there are no updates available, try disabling extensions one-by-one and then running Firefox normally. Using a process of elimination you can find the source of the lockups and uninstall or permanently disable the extension.
