Firefox will not open. Can't update or delete. Says it's already open and I am unable to find how to close it.

Firefox shows notice that it is already open and must be closed in order to update or delete. I can't locate a place to close the process. It's probably something very simple but I am not a computer genius. Thanks!

Have you tried looking for firefox.exe in the Processes tab of Task Manager (you can get to that by using Ctrl-Alt-Delete, usually)? If you click on firefox.exe in that list and then click End Process, it should close Firefox, even if Firefox doesn't appear to be running (sometimes the process takes a bit longer to close than the main window). If all else fails, perhaps a reboot?

Thanks Sionnach!!! I love you! :O) Ctrl-alt-delete did it. :O) I had tried to reboot and that did not work. Thanks for your expertise. Have a nice evening!
