Hi, these programs open MHT files. Please start opening and converting them for use with Firefox.

Firefox never had a feature to open MHT files on its own, but that was added by one or two legacy extensions. Firefox 57+ can no longer run legacy extensions, and I don't know of any new extensions that can read MHT.

Also, I don't know of any programs for Mac that open MHT files, other than maybe Microsoft Word.

But I saw a tip on a Mac site to change the .mht file extension to .eml so that Apple Mail or your default email program opens the file. The reason is that apparently MHT is the same encoding as EML.
