  • Use "Firefox/File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit") to close Firefox if you are currently doing that by clicking the close X on the title bar.
  • Wait a bit longer before reopening Firefox to give Firefox more time to close completely.

You should update your no longer supported Firefox 5 version.
