Firefox already running error - but can't end the process.
Hello, often after waking the PC from sleep and trying to search for something, it is stuck on loading the web page/search. So after I close Firefox and try to open it again, it says it is already running and must be closed. If I click on Close Firefox, the dialog box closes for a while but reappears with the same message. When I want to kill the process with Task Manager, it says Access is denied, and the only way to open Firefox again is by restarting the PC.
