The HTML5 Extension for Windows Media Player Firefox Plug-in is an add-on that enables Firefox users to play H.264-encoded videos on HTML5 pages by using the built-in capabilities found in Windows 7. This Extension adds to the functionality of the extremely popular earlier Windows Media Player Plug-in for Firefox to enable web pages that use the emerging HTML5 standard.

Firefox has issues with H.264 and its patent-protected technology (even though, users will be allowed to encode HTML5 video using H.264 for free, forever) and has refused to allow HTML5 videos encoded using H.264 to playback in its browser because of its policies. And then *Microsoft* release this.

*Microsoft* of all companies, release a *Firefox* plugin that enables H.264 video! (Okay, albeit for Windows 7). #whowouldvethunkit I gotta say, I've been very impressed with Microsoft over the past few months. First Windows Phone 7, and now this. Very impressive.
