When I want to open the Firefox after closing it, It says "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".
So, I always have to go to the Task Manager and end the process. Why does it happen? How can I fix it? Thanks a lot.
