Why is Firefox continuing to run after I shut down the internet connection?
I am having a problem with Firefox not shutting down. I shut down the internet, then go back on later and I get an error message that Firefox is already running and that I will need to reboot my system to clear the problem. I am running Firefox 3.6.17 on Windows Xp with sp3. I tried running Firefox 4.0 and it just did not run at all so I went back to the previous version.

Hanging at exit is usually caused by and Extension or Plugin.
Sounds like it is hanging when you exit and later try to restart Firefox.
- How to stop the running Firefox process
- In Task Manager, does firefox.exe show in the Processes tab?

- What may cause Firefox to hang at exit
- You may need to try Firefox Safe Mode
- You may need to use Safe Mode to locate the problem:
- See:
- Firefox 4 users, hold the Shift key while clicking the Firefox 4 desktop icon to enter Safe Mode.
- Firefox Safe Mode is a diagnostic mode that disables Extensions and some other features of Firefox.
- In Firefox 4, Safe Mode also disables Plugins and Hardware Acceleration.
- If you are using a theme, switch to the DEFAULT theme: Tools > Add-ons > Themes before starting Safe Mode (In Firefox 4, Tools > Add-ons > Appearance). See: http://support.mozilla.com/en-US/kb/Using%20themes%20with%20Firefox#w_managing-themes-and-personas
- When entering Safe Mode, do not check any items on the entry window, just click "Continue in Safe Mode".
- Test to see if the problem you are experiencing is corrected.
- If the problem does not occur in Safe-mode then disable all of your Extensions and Plug-ins and then try to find which is causing it
- by enabling one at a time until the problem reappears.
- You can also enable a few at a time (3-5), keeping track of what you just re-enabled to see if the problem re-occurs; this will help narrow down the possibilities if you have a large number of add-ons.
- You MUST close and restart Firefox after EACH change via File > Restart Firefox (on Mac: Firefox > Quit).
- You can use "Disable all add-ons" on the Safe Mode start window.
