Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window.

What is your computer system and Firefox?

What you describe sounds like the computers CPU is being overworked.

Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac=Options)
key, and then starting Firefox. A small dialog should appear. Click Start In Safe Mode (not Refresh).

Is the problem still there?

Please make sure Firefox has the time to closedawn properly. Sometimes it runs in to problems. If it fails to closedown properly, it then may have problems trying to start up normally.


Try to make sure you close Firefox by using the Firefox menu button then the quit button. Allow it at least ten minutes to closdown before considering powering off the computer or closing down the Operating System.

Are you getting crashes ?
