After deleted profile my Firefox will not start Message - 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 have tried – Restarting - Checking control panel for active firefox.exe –Uninstal l- Reinstall- and run CCleaner. All without any result

Can You help me? Are there any other processes that can be running? Is there any cleaning tool available?

Best Regards, Pelle

Hi Pelle,

Why did you delete your profile? Also how? Did you use the profile manager or did you delete from the windows file structure?

It sounds like something during the profile delete has stopped Firefox from starting up. Please see the this article and follow the steps: Please see this article: http://kb.mozillazine.org/Profile_in_use

That happens if you delete the Firefox Profile Folder but leave the profiles.ini file.

The solution is to use the Profile Manager and delete that no longer present profile and create a new profile or delete the profiles.ini file.
