I get this message when i try to start a Firefox:

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 did restart many times but it is a bogus message because there isn't any other copy running, for sure.

You can check if you still have a (default) profile folder as listed in profiles.ini.
If not then delete profiles.ini and let Firefox create a new default profile.

Thank you!

That worked!

I lost my bookmarks, but now I have a functional firefox.

Thanks a bunch.
