What you ask is after all possible in MAF, even though the feature is not immediately accessible at present.

* Select Tools » Mozilla Archive Format » Preferences
* Select File associations
* Click "Create association for .mht and .mhtml extensions"

If you need more support or have other questions, feel free to contact me through the project's feedback page (http://maf.mozdev.org/feedback.html).
