When I try to start Firefox I get Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system.
I get this message when I try to start Firefox after first logging on after turning on the computer.
Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system. Have rebooted. Works when Administrator logs in, just does this in my user profile. Have also re-intalled. Mo change in my User account. Firefox was working fine for the last 3 1/2 years. Any suggestions?

Firefox is "hanging at exit" when you exit/quit Firefox.
- Stop the Firefox process:
- Mozillazine - Kill application
- Windows 7 users click here
- Mac users: http://techheavy.com/2011/02/the-mac-task-manager/
- Why Firefox may hang:
- Firefox hangs (see Hang at exit)
- Firefox hangs (Mozillazine) (see Hang at exit and Closing Firefox properly)
- Firefox is already running but is not responding
- Use Firefox Safe Mode to find a problem with an Extension or Plugin:
- Don't check anything when entering Safe Mode, just continue
- If the problem does not occur in Safe Mode it is probably and Extension or Plugin causing the problem
