Your plugin list shows that the Firefox WPM plugin (np-mswmp) is installed. It's possible that the test page in the Play Windows Media files in Firefox with the Windows Media plugin article isn't working. (I can't tell since I'm using Mac OS X with the Flip4Mac plugin. The np-mswmp plugin is Windows-only.)

Try this other Windows Media Player plugin test page:

(You may have to wait a minute or so for the embedded content to load; then a brief "countdown" animation should display)

Not related to your problem, but you might want to consider upgrading to a more current version of Firefox, unless you have a specific reason for using Firefox 3.0.x. The last version of the Firefox 3.0.x series (no longer supported or updated, even for security issues) was Firefox 3.0.19 which was released on 03/15/2010.

Read this carefully: http://support.mozilla.com/en-US/kb/Upgrading+to+Firefox+3.6

The current version is Firefox 3.6.11

Whether you upgrade your browser or not, you do have out-of-date plugins with known security issues. You should upgrade/update your plugins.
