I'm using Windows 10. Out of the blue yesterday, when I tried to open Firefox, I get a message saying "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window." Choices: Close Firefox or Cancel. Before doing anything else, I verified in Task Manager that there were no processes running for Firefox. Then I click "Close Firefox". Get Profile Missing message box saying "Firefox profile cannot be loaded. It may be missing or inaccessible ". I then verified that I do have a default profile in the proper folder. What now?

My profiles.ini file is missing. Can it be recreated?

Update: I found the profile.ini in another folder? And no, I have no idea how it got moved ;-) I'm back up and running.

Thanks for your help!

hi ClareO, please go to %appdata%\Mozilla\Firefox\Profiles - in this folder you should find a file named profiles.ini which contains the path to your profile which the application will use. please check that the path within profiles.ini matches your actual folder...

I have the same issue of thunderbird not shutting down and the lost profile error message. I have no idea where to look for my profile and wouldn't recognize it if I saw it. I tried rebooting, but that didn't work. Even reinstalled Thunderbird with no affect. Any thoughts?
