MHTML is not usually supported as a brower format. It's an output
format: combining HTML, CSS, JS, and images into a MIME-compliant
(sorto) single file archive format. There are some readers, and
converters to put files into more common document formats. A dated
Wiki article lists some:
https://en.wikipedia.org/wiki/MHTML#Browser_support I just created an
MHTML file in GNOME Web, read it in a text file reader, and failed to
get it to display again in GNOME Web. The file starts:
From: <Saved by WebKit>
Subject: TR&A Home Page
Date: Sat, 27 May 2022 17:17:51 -0400
MIME-Version: 1.0
Content-Type: multipart/related;
type="text/html";
boundary="----=_NextPart_000_97B1_0143DBAC.3B903B8E"
------=_NextPart_000_97B1_0143DBAC.3B903B8E
Content-Type: text/html
Content-Transfer-Encoding: quoted-printable
Content-Location: https://www.tedroche.com/
In my experience, some browsers can create an MHTML file, but few can
read it. An email (.eml) file reader can, though.
What is it you are trying to accomplish?
Note, too, that the format has several known exploits:
