Error message to close firefox appears upon app launch and indicates that a copy of firefox is already open. How do I find the open copy and close it permanently?

When I go into my daughter's account and try to launch Firefox (she was previously using Safari) an error message pops up indicating to "Close Firefox: A copy of Firefox is already open. Only one copy of Firefox can be open at a time." Except that I don't see an open copy of the app, unless it somehow is launched at login, a setting I don't see either. Firefox works fine on other user accounts.

Is there still a default profile folder present?

  • /Users/<user>/Library/Application Support/Firefox/Profiles/<profile>/

If not then delete the file profiles.ini
That will cause Firefox to create a new default profile.
