Shame on you.

Was that an update straight from Firefox 33?

Or was that an installation where you jumped over a few versions? If so, which version were you using prior to the new installation?

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

Passwords are stored in the logins.json file. See if the file is still there;

Type about:support in the address bar and press enter.

Under the page logo on the left side you will see Application Basics. Under this find Profile Folder. To it’s right press the button Show Folder. This will open your file browser to the current Firefox profile.


This MAY recover an old password file.

Firefox 32 and later builds store the passwords in the logins.json file in the profile folder and no longer use the signons.sqlite file. You can force Firefox to reimport the passwords from the signons.sqlite file.

  • reset the signon.importedFromSqlite pref on the about:config page to the default value via the right-click context menu
  • delete the logins.json file in the Firefox profile folder with Firefox closed

When you restart Firefox then you should have the signon.importedFromSqlite pref with the value set to true and you should have the passwords imported in the Password Manager unless there may have been errors.

You can use this button to go to the currently used Firefox profile folder: Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)

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.

It was a "'password add on", that was no longer compatible with the last version. Consequently all the passwords were "invisible". Once it was removed as an add on, things reverted to normal with the password manager.

It was the very last version before, and the current update.

Yes, I use it myself.
