NOTE: Support for MP4 Downloader has been discontinued.

I don't have the time anymore to keep up with all the changes that YouTube, Dailymotion, and Vimeo make that affect video downloading, along with keeping up with the latest changes in Firefox.

The codebase has been left in the middle of a complete rewrite (see the Source Code section of the Development page). That codebase, and this website, are left here for archival purposes.

About

MP4 Downloader is a simple, cross-platform, open-source browser add-on that downloads videos from YouTube, Dailymotion, Facebook Video, and Vimeo as MP4 files. This add-on can currently run in Mozilla Firefox (as an add-on) or in any browser as a bookmarklet.

A good reason to download videos in the MP4 format is that this format is iPod-compatible without additional conversion. All videos downloaded using MP4 Downloader can be easily transferred to an iPod (or almost any other portable device). See the Sync to iPod page for details.
