Suddenly all of saved passwords are gone on my pc. How can I get back them?

All saved passwords disappeared suddenly. It's there, but I restart my PC and open my Firefox and none of them are there.
How should I restore them?

The extension 'Remember password' has been reported to cause problems with passwords disappears, so if you have this extension and then remove (uninstall) it.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/tools > Modules > Extensions) or if hardware acceleration is the cause of the problem.

  • Put yourself in the DEFAULT theme: Firefox/tools > Modules > appearance
  • Do NOT click on the reset button on the startup window Mode safe

You would need a copy of backup of the files logins.json and key3db (eencryption key) If passwords are really gone.
You can check the logins.json file to see if the file contains documents from password.

You can use this button to go to the Firefox profile folder currently in use:
