Three days ago Firefox froze and wouldn't allow me to do anything. I quit and then Firefox would not open. Went back to Safari and download the latest version of Firefox, and installed it. It started by saying that Firefox was already running (it wasn't) so I forced it to quit. Installed and asked it to replace the existing version. Then I tried to run it and it told me that it was already running!!!
Short of deleting the whole application and starting again - losing bookmarks, passwords, etc. - what else can I do?
/edit: moved thread from Firefox for iOS (for iPhone/iPad) to Firefox as this both sounds like desktop version and you put in "Mac Ventura v13" in system details on right so you have macOS.
