K-Meleon
NOTE: The Windows Media Player Plugin for Netscape is no longer supported by Microsoft, Netscape, Mozilla, or K-Meleon. It is more secure to use an external application like VLC.
The Windows Media Player Plugin is an NPAPI plugin to play media files from K-Meleon. It may be included in older versions of windows. You can check if you already have the plugin available by typing about:addons into the address bar and navigating to plugins.
K-Meleon will automatically detect many versions of the Windows Media Player plugin. However the Windows Media Player 11 installer has a bug that may prevent this. If you have Windows Media Player 11, copy np-mswmp.dll to your browser plugins folder. Windows Media Player 12 and up no longer provide plugins, so the library must be downloaded. You can download np-mswmp.dll from K-Meleon Extensions Central here: http://kmext.sourceforge.net/mplug.htm
