Try the Firefox SafeMode to see how it works there.
When in Safe Mode...
- The status of plug-ins is not affected.
- Custom preferences are not affected.
- All extensions are disabled.
- The default theme is used, without a persona.
- userChrome.css and userContent.css are ignored.
- The default toolbar layout is used.
- The JIT Javascript compiler is disabled.
- Hardware acceleration is disabled.
A troubleshooting mode, which disables most Add-ons.
(If you're not using it, switch to the Default Theme.)
- You can open the Firefox 4.0+ SafeMode by holding the Shft key when you use the Firefox desktop or Start menu shortcut.
- Or use the Help menu item, click on Restart with Add-ons Disabled... while Firefox is running.
Don't select anything right now, just use "Continue in SafeMode."
To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut (without the Shft key) to open it again.
If it is good in the Firefox SafeMode, your problem is probably caused by an extension, and you need to figure out which one.
