After closing FireFox and then try to reopen it I get a message that FireFox is still open and that I need to either close the program or restart my PC. FireFox does not show that it is open on the task bar or the Task Manager. I restart the PC and then open FireFox. After I close FireFox I get the same error message and have to restart the PC to open FireFox again.
