Where can I get the Mozilla Archive Format to open .mht files?

I'm trying to find a way to use Firefox as the default browser for .mht files, but the links here are broken: https://support.mozilla.org/en-US/questions/968422

Where can I find the unmht addon or the Mozilla Archive Format?

That thread is from 2013...

As you may know, many extensions released before Firefox 57 (November 2017) used features (legacy APIs) that are no longer available to extensions in Firefox 57 and later (WebExtensions APIs).

I don't know whether there are any new extensions to decode .mht / MHTML files. Have you searched on the Add-ons site?

I searched the add-ons, but couldn't find anything related to .mht files or Mozilla Archive Format.
