Mozilla Archive Format

Save complete web pages in a single file, using one of the following formats:

MAFF (Mozilla Archive Format File)

MAFF files are standard ZIP files containing one or more web pages, images, or other downloadable content, like video and audio. Additional information, like the original page address, is saved along with the content; this metadata allows the browser to open these files intelligently.

For example, you can save to disk all the open tabs at once in a single MAFF file.

MAFF files are not proprietary, and once saved with Firefox they can be opened on any modern computer system, using your favorite ZIP extraction utility. Moreover, since you can batch-convert MAFF files to other formats at any time, should you ever need it, there is really no risk of vendor lock-in. Learn more...

MHTML (Internet Explorer's MHT)

MHTML, or MIME HTML, is the file format used by Internet Explorer when saving web archives. The Mozilla Archive Format extension allows Firefox to open and save these files seamlessly, providing full interoperability with Internet Explorer.

MHTML can only contain a single web page and its subpages. Learn more...
