A MAFF file is a Zip-compressed archive created by the Mozilla Archive Format add-on for Mozilla Firefox and SeaMonkey. It contains one or more saved webpages and files to view them offline. The MAFF file format is open and the specification is published.
Existing MAFF files can be accessed by extracting the folders and files with an archiver like 7-Zip. Pale Moon allows opening .maff files in Windows. MAFF is compatible with software for Linux, Mac, and Windows. The most popular program to handle MAFF files is Mozilla Firefox.
The MAFF file extension indicates an archive format. The archive can contain documents, spreadsheets, notes, and more depending on the software used to create it. To open a MAFF file, suitable software like the Mozilla Archive Format Extension is required. Without it, Windows gives an error that it cannot open the file.
MAFF files can also be opened by changing the extension from .maff to .zip and using any Zip extraction utility. The original Mozilla add-on provided a procedure to convert between MAFF and other formats. MAFF files store required web content together in one file so the pages can be viewed offline as they appeared online.
