"Firefox already open" msg prevents launching browser
Using with OS 10.12.6 Tried using Refresh Firefox, then was unable to open the browser, with a message "Close Firefox" indicating the a copy as already open. I have tried rebooting, deleting and reloading Firefox, opening in Safe mode, etc, without success.
