I recently visited some web sites which needs Windows Media Player for their multimedia contents. FireFox complained about x-mplayer2 plugin not available. I found this page which solves my problem.

The solution is easy. Just download these two files ( npdsplay.dll and npwmsdrm.dll ) . Copy the files to FireFox’s plugins directory (mine is in C:Program FilesMozilla Firefoxplugins ). Restart FireFox and you are done.
For those who don’t trust dlldump.com, you can download the plugins directly from Microsoft.com. Here is the link. After installation, the plugins are in “c:Program FilesWindows Media Player” directory. Just copy the files to the FireFox’s plugins directory.

Thanks for posting that. Copied the two dll’s, just in case, so Firefox hasn’t to complain that much 😉
That’s great, thanks for the post firefox works a treat now!
“PERFECT!!” Worked as stated above! “HUGE THANKS!”
i cannt install media plugins that was writen above.
Bdshipon,
If you have problems installing the plugins, just copy the two files over the FireFox plugin directory manually.
How do you install those two .dll files on a Mac computer?
Jason,
The files are for Windows only. You need to download the WMV component from Microsoft for your Mac.
