Mozilla Archive Format, with MHT and Faithful Save

保存した Web ページを Internet Explorer など他のブラウザで開く (MHT)、タブで開いているすべてのページを、画像なども含めて 1 つの ZIP ファイルに保存する (MAFF)、保存したページから元のサイトへ戻るなど、便利なアーカイブ機能を提供します。



This extension enhances the way web pages are saved on your computer.

It provides the following advantages over the built-in save system:
— A complete page can be saved as a single file (web archive)
— You can name files using the title of the page (title save)
— The saved pages are faithful to the original (exact save)

You can view and save MHT (MHTML) files, with excellent compatibility with Internet Explorer;
but more importantly, you can use the MAFF file format, with the following advantages:
— Save disk space, since MAFF files are compressed
— Include video and audio embedded in the pages
— Be universal, since MAFF is based on ZIP and compatible with Linux and other platforms
— Use an open format, with no risk of vendor lock-in

The MAFF format is exceptional when combined with the built-in browser support for the Ogg Vorbis and Ogg Theora media formats in web pages: you can save everything in a single file. You can even save more than one tab in a single MAFF file.

The MAF extension allows you to convert your already saved pages to the format of your choice. You can use this feature to save disk space, or even to convert MAFF to the other formats, should you ever decide to go back.

MAF also interoperates with other extensions, for example:
— Multiple Tab Handler (easily select the tabs to save)
— UnMHT (additional expert features to read and write MHTML)

The MAF extension is intuitive and easy to use, but empowers you with advanced features: see the user manual if you want to find out more!

• In order to open MHTML files when the IE Tab extension is installed, the filter /^file:\/\/\/.*\.(mht|mhtml)$/ must be disabled from the IE Tab options.
• The Download Sort extension has a known incompatibility with MAF. The conflict cannot be resolved without proper modifications to both extensions, and Download Sort is not actively maintained at this time.
• The integrated Save Complete extension cannot always save pages with dynamic contents correctly.
• When saving a page in an archive fails, retrying the download from the Downloads window does not achieve the expected result.
• Opening very long documents contained inside MHTML files may cause the browser to stop responding temporarily.
• With versions of Firefox prior to 3.5.3, web archive files must have a lowercase file name extension in order to be opened.
