Why does Firefox get rid of all my new tab settings whenever my computer crashes on it??

For vague reasons, my computer crashes and reboots every other day whenever I try to turn it on. I would do something about that, but most of the laptop settings are behind a parental admin lock. So when Windows reboots, any Firefox window gets closed. Opening it back used to prompt a session restore page and nothing else. But now, reopening causes these symptoms: I'm logged out of "Sync" There's a tab about a Privacy Notice or something There's a 'new tab' with a popup talking about the features of Firefox or something Any Top Sites I pinned are GONE "@amazon" is pinned for no reason I think my search sites settings are gone Pretty sure I added a search bar to the toolbar, but not anymore The theme reset to this default dark blue Signing back into Sync does not solve any of this What do I do about this madness???

Hi toranporin, sorry about this. After Firefox 67 was released, users noticed that some settings files were more fragile in a system crash. There are some fixes for this in Firefox 68, but it may not be completely cured.

One of Firefox's main settings files is called prefs.js and it stores settings such as your pinned tab addresses, and toolbar layout. You might wnt to start backing up this file from time to time so you can pop it back into your profile folder when needed. This article has more info on what to back up: Back up and restore information in Firefox profiles.

Question, though, why would Firefox be running at Windows startup? If startup is crashy, it probably would be helpful to Exit Firefox using the menu command, either --

  • "3-bar" menu button > Exit
  • (menu bar) File > Exit

-- before you shut down Windows, to bypass the automatic resumption feature in Windows 10. (There's also a setting for that: Firefox starts automatically when I restart Windows)
