Windows Media Player Plug-in for Firefox

by hjanssen on April 16, 2007 04:04pm

A few weeks ago I wrote a blog called ‘We're Writing Firefox Plug-ins? Interview with Ian Gilman and Thoughts on 10 Months at Microsoft’ (Who came up with that title anyway!)

In which I chronicled my first 10 months on the job. Also in there I mentioned Microsoft writing plug-ins.

Well today I am very proud to announce that we have released another official Microsoft plug-in. It shows another level of interoperability and eagerness in working with the Community to get this released.


This plug-in allows you to use Windows Media Player inside of Firefox. It is designed to support the following Windows platforms;

  • Windows XP SP2 (x86)
  • Windows XP SP2 (x64)
  • Windows Vista (x86)
  • Windows Vista (x64)

Port25 is hosting it, and you can download it from here; Windows Media Player Firefox Plugin - Download

It was put together by the Windows Media Player team, and special thanks go to Eric Anderson and Thobias Jones. (And all the other people in the Windows Media Player team). I also wanted to thank Mike Schroepfer and the Mozilla Foundation in helping us get this released.

From now on when you go to the plug-in site at Firefox, you will be automatically routed to Port25 to download and install the plug-in.

It is backwards compatible with the old 6.4 Windows Media Player. And among other things has the following new features;

  • New robust design that addresses all of the known issues with the old plug-in
  • Windows Media Player will now work with Firefox on Windows Vista
  • Support for the Windows Media Player OCX scripting interfaces

We will post some links to example code in the next few days to help people use some of the new features.

Install it, and to test it just go to Port25 and check out any of the videos.

    But how can I install WMP – plug in for FireFox 5.01-portable when using Windows 2000 (FF5.01-portable works on Win 2000) but not the Plug-in for WMP as Windows 2000 only plays WMP 9.0

    Thank you so much for this post.  I have spent my entire evening trying to figure out why streaming .wmv files would play in IE but not in Firefox.  I got advice ranging from installing additional codecs to changing registry keys and dozens of other useless suggestions.  Turns out I only needed to read your four year old post in order to solve the problem.  Thanks.

    Hi, It is possible to update it to support Firefox x64? This is only extension, that limits me to switch to 64 bit browser 🙂 Thanks

    What a worthless piece of junk unless you were unlucky to have bought Win. Vista which IMO is a cousin of Win ME.  I do not even use Firefox only IE9 & latest version of Chrome so this plugin is no use to me & I will uninstall it ASAP!
