I have this Mozilla Archive Format, with MHT and Faithful Save addon installed with Iceweasel on debian 8.3 jessie stable. The addon is useful in saving webpages into single file with extension maff.
The mimetype for this maff file is
application/zip. Because of this, whenever I open maff file, it opens in
Archive Manager or analogous application.
In order to open maff files in iceweasel, I have chosen
Open with Iceweasel in file properties. Doing so opens maff files with iceweasel, but also opens every zip file in iceweasel with a download dialogue box. I think this is because the system has set mime type
application/zip with iceweasel.
All I want is to open maff files with iceweasel/firefox and open zip files in regular Archive Manager. How can I achieve this?
