I saw the article by Alice Wyman regarding this issue. What seems odd about my situation it just really started last week. When I shut down at the end of the session I always close the browser before I power off. It doesn't happen all the time about 30-40% of the time. I've also notice that when I run CCleaner I will get the message that FF is open and needs to be closed , again, about 30-40% of the time. I've never had this issue with Chrome. So I'm wondering what is different or what may have changed regarding my issue? I look foward to anyone's comments. Thanks

Are you using "Clear history when Firefox closes" to clear session data?

Do you give Firefox enough time to close properly before you power down the computer?

Try to wait at least one minute and check in the Windows Task Manager whether there are still Firefox processes left.


Try to use one of these to close Firefox if you are currently doing that by clicking the close X on the Firefox title bar.

  • "3-bar" menu button -> Exit (Power button)
  • Windows: File -> Exit
  • Mac: Firefox -> Quit Firefox
  • Linux: File -> Quit
