Firefox will not re-start without "ending process" with Windows Vista Task Manager.

Posted

Error Message: “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.”

Have to start Task Manager and then end firefox.exe process.

Thanks all.

The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Note: This will cause you to lose any Extensions, Open websites, and some Preferences.

To Reset Firefox do the following:

  1. Go to Firefox > Help > Troubleshooting Information.
  2. Click the "Reset Firefox" button.
  3. Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
  4. Firefox will open with all factory defaults applied.


Further information can be found in the Reset Firefox – easily fix most problems article.
