mozilla-gnome-keyring

A mozilla extension to store passwords and form logins in gnome-keyring

This replaces the default password manager in Firefox and Thunderbird with an implementation which uses Gnome Keyring. This is a centralised system-based password manager, which is more simple to handle than per-application management.

You need libgnome-keyring0 to be installed, for this extension to work. When this extension is enabled, passwords stored in the default password manager are not accessible. See migrating old passwords for an efficient set of instructions to manually work around this.

You can find more technical information on bugzilla issue or on the github project pages.

Usage

You can change the keyring in which passwords are saved by creating or editing the preference item extensions.gnome-keyring.keyringName. The default keyring is mozilla. This is a per-profile setting, so if you don't manually change it, all profiles will share the same keyring.

You can backup your passwords easily, separately from the rest of your mozilla profile. Your keyrings are stored ~/.gnome2/keyrings - even gnome-keyring 3.0-3.16 does this, though this may change in the future.

You can also take advantage of the more fine-tuned keyring management features of gnome-keyring, such as:

  • No need to prompt for password, if you store in the login keyring and the password for that keyring is the same as your login password.
  • If the keyring is already open, don't need to prompt for a password each time you start Firefox or Thunderbird.
  • You can explicitly re-lock the keyring when you feel you need to.
  • In gnome-keyring 3, the keyring password prompt disables keyboard input to other windows, so you don't need to worry about accidentally typing it somewhere you shouldn't

Note: gnome-keyring stores the passwords encrypted on permanent storage but it keeps unlocked passwords in memory without encryption. As a result, programs with access to the memory space of gnome-keyring (such as debuggers and applications running as root) may be able to extract the passwords. The same applies to the default Firefox and Thunderbird implementations, so this extension should not be any less secure.

Non-working cases and workarounds

Passwords will not be saved or filled in if:

Actually, these issues are all browser issues, and not directly fixable by this extension.

Migrating old passwords

This extension cannot migrate passwords on its own. However you can use the Password Exporter extension to export your passwords from the default password manager and then re-import them into gnome-keyring:

  • Before installing this extension install the Password Exporter extension.
  • Export all the passwords saved in Firefox' password manager to a XML file.
  • Install this extension and restart Firefox.
  • Import the passwords from the previously exported file. They will be stored in the keyring specified by extensions.gnome-keyring.keyringName.
  • Once you're done, you are free uninstall the Password Exporter extension and shred the XML file.

The old data of the default password manager remains untouched, so you also need to delete that manually if you want to. This is done by going to your profile folder, and shred-ing key3.db and signons.sqlite. After deleting, the data may still be forensically retrievable from your disk, but if you were protecting it with a master password, this data would still be be encrypted.

Deleting old data will also clear the master password for the default password manager. If you don't clear it, you'll still be asked for it when you choose to "show passwords", even if this extension is active.
