I can not get Firefox to play music backgrounds on pages in browsers it works in IE and other browsers but not firefox, what HTML or Jave script do I need too use to make them work?

I'm having a problem with firefox playing background music on some sites, it works with IE and other browsers but not with fire fox, what html or java script do I need to add to the pages so that they play the music? I develop my pages in Front Page and I know that the music only works in IE, so if someone can tell me how to correct this problem as it is important as I use fire fox as my main browser. I thank you in advance
