Rated 5 out of 5 stars

For years I've been uncomfortable with the fact that Thunderbird stores its passwords in an unprotected file and that snooping software could recover plaintext passwords and oauth keys from it. Swick's excellent "GNOME Keyring integration" add-ons fixes that by allowing the user to have this information stored in a password protected encrypted gnome keyring file with a name of your choice (I chose "thunderbird").

The add-ons ties in to standard Gnome keyring tools, and I can easily lock the keyring (using the seahorse GUI) when it is not needed.

I'm using version 0.13 of the add-on with Thunderbird version 60.
