Player em JAVASCRIPT

Olá a todos, sou iniciante aqui no fórum do imasters, e gostaria que vocês me ajudassem a solucionar um problema com meu player em javascript.

O script para a trasmissão de aúdio funciona em boa parte dos navegadores, só que os botões só consigo que ele funcione no IE, queria uma ajuda pra que esses botões funcionassem pelo menos no FireFox.

Script postado abaixo:

<script language="JavaScript">

function clickIE() {if (document.all) {(message);return false;}}
function clickNS(e) {if

(document.layers||(document.getElementById&&!document.all)) {

if (e.which==2||e.which==3) {(message);return false;}}}
if (document.layers)

{document.captureEvents(Event.MOUSEDOWN);document.onmousedown=clickNS;}
else{document.onmouseup=clickNS;document.oncontextmenu=clickIE;}

document.oncontextmenu=new Function("return false")
