I've been having an issue with FireFox. I started up my PC, and clicked on FireFox, and it said there was already a window running please close or restart. Well I didn't see a window open, opened up Task Manager, and no program running so I restarted it. When I came back to my desktop, I clicked FireFox again and got the same message, "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 uninstalled and reinstalled FireFox. No luck. Any help?
