In case this mite be a problem and is still unknown by some.
Microsoft has released a Windows Media Player plug-in so the player works with Firefox 2.0 on Vista.
The new plug-in (download) for Firefox can be found at Port 25, which is Microsoft's communications hub with the open source world.

NOTE:
Quoting:
There is a known issue if you are using Firefox version 2.0.0.3 on Windows Vista with the installer failing with error code -203. To work around this simply restart Firefox (you will get a notification that Windows Vista will be changing the Firefox compatibility settings) and then install again - the second time should succeed.
