sometimes Firefox will not open, telling me, it is already running. It does not show in the task manager and the only solution is to reboot.

Firefox is running. I close the program. I try to reopen it. I get an error message: Firefox is already running. It does not show in the task manager, nor anywhere else. I can not close the old version, nor start a new one. I have to reboot.

Did you look in the Processes tab in the Task Manager?
