Be careful with old versions!
These versions are displayed for reference and testing purposes. You should always use the latest version of an add-on.
Support has also been added so you can toggle the
network.negotiate-auth.allow-non-fqdnconfiguration keys, allowing automatic pass-through auth for all non-FQDN hosts without having to specify every one explicitly. These settings are new in Firefox 13.
Also, this version adds an entry into the "Options" menu on the App Toolbar for Firefox 4.
