Crashes everytime I open the new version 4. I can't open it in safe mode as I do not have a safe mode in the folder. I don't want to uninstall as I think I will lose all my bookmarks?

1.You can open the Firefox 4.0 SafeMode by holding the Shft key when you use the Firefox desktop or Start menu shortcut.
2. Or use the Help menu item, click on Restart with Add-ons Disabled... while Firefox is running.
To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut to open it again.
