I have some mp3's on my page that are selected from a JavaScript menu that play fine in IE, but Firefox insist's that I don't have the proper plugin for to play in Firefox. It also identifies it as an unknown plugin and can't find or suggest one for me to install. I've noticed that the extensions for Media Player do not contain the extension mp3. Is there a way to add the extension? Or do I need to come up with some other JS to deliver the tunes? Or do I need to convert my songs into a playlist so that the it will play using the m3u extension which Firefox does recognize?
