Chosen solution

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

If you use "Clear history when Firefox closes" then try to disable this feature.

  • Options/Preferences > Privacy > Firefox will: "Use custom settings for history": [X] "Clear history when Firefox closes"

Note when closing down for now give Firefox at least 10 minutes before trying to kill or power off. Even longer if you can still see disk activity. If Firefox runs into problems trying to closedown it should timeout, and then start trying to generate and submit a crash report.

If you visit about:crashes do you see recent crash reports ? If so please paste in couple of the Crash IDs starting with bp-

the exit command did the trick, I'll remember that in the future. I never had that "erase history upon exit" setting on.
