Every time Firefox updates(like today), it wipes out my password list on the password manager; how do I find my passwords?

When Firefox auto-updated today(after it had crashed then restarted), all of my passwords in the password manager disappeared. These have been saved over several years and I don't have a copy of some of the older ones. How do I get my passwords back?

All passwords are stored in key3.db and logins.json however if they do not display in Firefox, it may no longer be there unless you have a back up.

  • Do you use another password manager besides the one built into Firefox?
  • What steps are you taking to update?

These can't get your data back, but will help in the future.

These add-ons can be a great help by backing up and restoring Firefox

FEBE (Firefox Environment Backup Extension) {web link} FEBE allows you to quickly and easily backup your Firefox extensions, history, passwords, and more. In fact, it goes beyond just backing up -- It will actually rebuild your saved files individually into installable .xpi files. It will also make backup of files that you choose.

The "Remember Password" extension has been reported to cause issues with the passwords disappearing, so if you have this extension then remove (uninstall) it.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

  • Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
  • Do NOT click the Reset button on the Safe Mode start window
