Firefox: good to know

If Firefox fails to start with this error message “Firefox is already running but is not responding” do this to fix it:

First check in your process list to see if firefox is already running and if it is, kill it ( the mozilla page rekommends that you reboot your computer but who wants to do that ).

If you can’t find any firefox process or you still get this message after you killed it, go into your profile folder ( ~/.mozilla/firefox/XXXX/ ) and remove ‘.parentlock’.

Now Firefox should be able to start successfully.
