Windows Vista, Firefox, and Windows Media Player 11

Windows Vista comes with Windows Media Player 11, and unfortunately this newest version of Windows Media Player doesn't works well with Mozilla Firefox (you can download from here), the alternative web browser that I mainly used now. When you use Firefox to try playing streaming video from web, it doesn't work because Windows Media Player 11 doesn't come with compatible plug-in for Firefox. Follow this link for detail explanation or just download and install the necessary plug-in from this link.
