The Mozilla Archive Format (MAFF) is a legacy web page archiving format provided by Firefox through an extension. It is used to save one or more web pages together 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.
The extension no longer works on newer (as of 2017) versions of Firefox. The author has stated that future support will not be added. But it is still supported in Cyberfox and Waterfox, forks of Firefox that try to keep features removed from Firefox like the traditional extension API. Browser extension WebScrapBook (with assistant PyWebScrapBook), available for Firefox 57+ and Chromium-based browsers, supports saving and opening MAFF files. Pale Moon extension MozArchiver, a fork of original extension, bring the same support for Pale Moon 26.0 and newer.
For those who have kept records in .maff format, one way to recover the file contents is to rename .maff to .rar, or .zip, then open the file with an unarchiver like 7-Zip, and extract the existing files and folders. It also allows for automatic processing, e.g. as ZIP-type in local search machines (like DocFetcher). Since MAFF is a well defined open file format, it makes sense to just keep the archived documents and use alternative extensions. At least Pale Moon allows to associate the .maff file type in MS Windows to open it directly with appropriate extensions.
