We're assuming it would still prefer you use Internet Explorer for all your web browsing needs, but Microsoft is now lending something of a helping hand to Windows 7 users that insist on using Firefox for one reason or another. It's just released a plug-in that gets around Firefox's current limitations in handling H.264-encoded videos on HTML5 pages by taking advantage of the H.264 support built into Windows 7. On a more technical level, that means the plug-in parses HTML5 pages and replaces the Video tags with a call to the Windows Media Player plug-in, which then allows the content to be played right in the browser. Sound like just what you've been waiting for? Hit up the link below to download the add-on and try it yourself.
