Mozilla Archive Format

The Mozilla Archive Format (MAFF) is a legacy Web archive file format that was provided by Firefox through an extension, used to store one or more web pages with their associated audio, video, and other related web resources to a single file. Unlike MHTML, which uses MIME encoding within a single HTML file, MAFF compresses the page into a Zip container file.
