Sometimes when you try to start firefox, it gives error “Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart the system” and exits. This problem occur generally because of unclean shutdown or power reboots. Whenever we start firefox it creates a lock or .parentlock file in your firefox profile directory(~.mozilla/firefox/profile/.parentlock etc) and because of unclean shutdown not able to delete the file.
