The installer for the Windows Media Player 11 browser plugin has a major design flaw!

Installers for Mozilla plugins should place the plugin files in the folder of the application they belong to, and information in the Windows registry so that all Gecko based browsers can locate the plugin. The Windows Media Player 11 plugin installer does not do this.

If Mozilla Firefox is installed, the plugin will be installed to your Mozilla Firefox plugins folder. If Mozilla Firefox is not installed, it will be placed in a \PFiles\Plugins folder on your Windows drive (usually C:).

If you wish to use the Windows Media Player 11 plugin with a browser other than Mozilla Firefox, copy np-mswmp.dll to your browser plugins folder.
