Steps to reproduce:

After updating Windows 10 Education 21H2, 19044.1466 - Windows Feature Experience Pack 120.2212.3920.0
Also caused an update of Firefox with the result that setup and all bookmax were deleted. I also could not use Firefox to log in using WAYF. I chose to uninstall Firefox and reinstall. Now Firefox will not run after rebooting windows. I get the following message: "Firefox is already running but not responding. The old Firefox process needs to be terminated to open a new window."
There are no Firefox processes running because there is a reboot and it is checked again moxilla processes.
What can I do to get Firefox running again?

Actual results:

After rebooting windows. I get the following message: "Firefox is already running but not responding. The old Firefox process needs to be terminated to open a new window."

Expected results:

That Firefox run.

1. Open File Explorer and paste the following into the address bar:
   %AppData%\Mozilla\Firefox\Profiles\
2. Open each profile folder and delete the parent.lock file.
3. If the problem persists, see the following support article for other possible solutions:

4. Your old Firefox data is probably in an old profile. See the following article for directions to recover it:

Hi

Thanks for the help. The help I have received from you does not lead me to a solution.

The solution / error was that my profile on PCs was made invisible. When I made my profile visible again, after a clean reinstall I could open Firefox again. I think my profile was hidden when updating Windows.

Close the case and thank you very much
