Disabling Tab Restore on OS Restart

I'm trying to stop Firefox from restoring tabs after I restart my OS. So far, I've done the following:

  • Disabled `Startup > Open Previous Windows and Tabs`
  • Disabled all extensions
  • Confirmed I do not have a `user.js` file
  • Set `browser.sessionstore.resume_from_crash` to `false`
  • Set `browser.sessionstore.restore_on_demand` to `false`
  • Set `browser.sessionstore.resuming_after_os_restart` to `false` (It was already set this way.)
  • Set `browser.sessionstore.max_resumed_crashes` to `0`
  • Set `privacy.clearOnShutdown.openWindows` to `true`
  • Set `browser.sessionstore.max_tabs_undo` to `0`
  • Set `browser.sessionstore.max_windows_undo` to `0`

(I've since reverted the last two and the extension changes after they didn't work.)

So far, Firefox will not restore tabs on application restart (manually closing and relaunching) or on crashing (after sending SIGTERM/SIGKILL), but it still restores tabs after restarting the OS (if I allow the OS to kill it during shutdown). I've seen a couple suggestions to disable history completely, but I do occasionally refer to my browsing history, so I'd prefer a less-drastic approach. Ideally, I just want Firefox to treat the first launch after a shutdown as a normal launch and not apply any special behavior. Any help would be much appreciated!

So... I managed to figure this out immediately after posting... The "See Also" section of this forum found what the search bar and google could not!

For anyone else who finds this: Relevant Thread Bugzilla Issue

My fix: To get around the underlying behavior, I went to the profile directory (Help > More Troubleshooting Information > Profile Directory) and created a `user.js` file with the following content: ```

user_pref("browser.sessionstore.resume_session_once", false);

``` This reverts Firefox's settings change every time the browser is launched. This probably breaks some other features (like tab restore when loading into debug mode), so use with caution. I'll maybe try to see if I can find a way to set this through a script that I can run on startup, but for now, this solves my problem.
