Every time I try to start Firefox . I get" Firefox is already running but is not responding and you must close it to start a new window". Problem is it's not running and when I do close it with the button " close Firefox" The error just comes back up. In all these years I've never had one issue until now. I also hate having to use edge or google. I've uninstalled reinstalled, cleared cookies and cache. I have windows 11 pro. I'm hoping someone will have run into this and knows what to do! Thanks Dan
