I need to find a Firefox browser plugin called Authenticator or Google Authenticator or GAuth
I would like to set up two-factor authentication (2fa) with my Nominet UK account (http://www.nominet.uk/). I would prefer to use desktop-based authentication rather than using a mobile device. Nominet have six supported options, but only one of them is desktop-based: "Firefox browser plugin" (see screenshot). Despite thorough searching I have been unable to find this plugin; the only thing I can find that might fit the bill (https://marketplace.firefox.com/app/gauth/) says "not available for your platform" and appears to be an HTML webapp rather than a plugin.
Nominet have not been able to help me with this and suggested I contact Mozilla – hence this question. Can anyone help me to track down this elusive plugin?
Sorry, the screenshot I posted didn't appear for some reason. Here it is (I hope!):
See if this web search helps; https://www.bing.com/search?q=Authenticator&pc=MOZI
Thanks for the suggestion, but no, it doesn't yield any relevant results. I did find the Firefox GAuth Authenticator add-on, which is probably what Nominet are referring to, but that add-on no longer exists, alas.
