You guys dropped MHT / MHTML. Why? Game Changer. Back to Opera. Why would I want a folder of web page stuff when I am saving something for reference?

I would like UNMHT back. MHT/MHTML should be native to the browser anyway without an add on. I use this all the time for saving engineering notes off the web.

Thanks guys!s

Mozilla never supported MHT / MHTML

Proposed by Microsoft in 1999 as a "standard", but never made thru the W3C standards organization and remains a proposed standard of W3C.

Firefox users have always needed MAFF or UnMHT extensions for that feature.

Try this extension: https://addons.mozilla.org/en-US/firefox/addon/save-page-we/

I also have this problem. I was able to save to MHT until a FireFox update killed the addon I was using.

I have to use Chrome at work because I need to save to MHT.

Is there an MHT addon coming soon????
