I don't think it was ever native in Firefox, there is/was the excellent unMHT extension that was broken by Quantum/WebExtensions and The Great XUL Silliness. Shame.
I have Waterfox-Classic and unMHT (fished out of the Classic Addons Archive, just remember to turn off Waterfox's multiprocess feature) since I occasionally need to archive web pages - and more importantly, reopen them later.
mhtml is just MIME, literally every discrete URL as a MIME part with its origin in a Content-Location header, all wrapped in a multipart container. I don't understand why it's not a default format.
- Groxx 5y agoI can see WebExtensions breaking it (as it's a completely new set of APIs for extensions, and the losses do definitely still hurt)... but quantum/xul? How is that related, aside from "it happened around the same time"?
- mrspuratic 5y agoIANA firefox dev: XUL/XPCOM = old APIs, WebExtensions = new (multi-browser) API Quantum was the the project name to re-engineer Firefox internals, with lots of design changes, not just plugins. XUL/XPCOM APIs were dropped, as an occasional programmer I understand why, "Quantum broke my plugins" is a reasonable first approximation for most users.
