Review for UnMHT by Terry
Rated 3 out of 5 stars
Appears to allow provide a lot of functionality, with many detailed options. Browser integration needs improvement, however. For example, instead of simply adding a new file type to the existing Save As dialog, a new "Save As MHT" entry is added to the File menu.
This review is for a previous version of the add-on (5.6.0).To create your own collections, you must have a Mozilla Add-ons account.
