Can't exit mozilla

Mozilla Firefox is not working. It worked fine yesterday and I haven't knowingly installed anything since. I can't uninstall it because I keep being told that it has to be closed before I can uninstall it. BUT it's not open!!! I am well and truly stuck! It opens and works in safe mode but just won't open in normal mode. PLEASE HELP!

Hello nickyfrance, have you tried restarting your operating system to see if firefox works fine?

You can also try this. It's not the regular way though. 1. Go to computer. 2. 2x Click Local disk :C. 3. 2x Click Program Files (x86). 4. Locate and find ALL Mozilla files and delete.

Same with Mozilla Maintenance. 1. Go to Control Panel. Open Programs. 2. Uninstall Firefox. It will, not be able to but it will ask to remove all of its features. 3.Click yes.

Do the same for Mozilla Maintenance. DONE!

Please do not try these steps:

These steps will erase Firefox from your computer and any bookmarks/personal saved data you had in Firefox.

@benjamindmanford: Please don't suggest doing anything to Mozilla files ESPECIALLY deleting. This is not recommended to users at all since they might delete an important system file and render their system unusable.


As for your issue with Firefox, it may be running in the background. Read How to close Firefox when it says it's running.

Re: Can't exit mozilla

It is possible that your security software (firewall, anti-virus) blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.

Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

See:


Do a clean reinstall and delete the Firefox program folder before (re)installing a fresh copy of the current Firefox release.

Download a fresh Firefox copy and save the file to the desktop.

If possible uninstall your current Firefox version to cleanup the Windows registry and settings in security software.

  • Do NOT remove personal data when you uninstall your current Firefox version, because all profile folders will be removed and you lose personal data like bookmarks and passwords from profiles of other Firefox versions.

Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.

  • (32 bit Windows) "C:\Program Files\Mozilla Firefox\"
  • (64 bit Windows) "C:\Program Files (x86)\Mozilla Firefox\"

Your bookmarks and other personal data are stored in the Firefox profile folder and won't be affected by an uninstall and (re)install, but make sure that "remove personal data" is NOT selected when you uninstall Firefox.

If you keep having problems then also create a new profile.

I have done that Moses - useful tip! I have now uninstalled Firefox and reinstalled it but it is still not working. What can I do now?
