Replace your <body> tag with this:
Code:
<body oncontextmenu="return false;">
Problem is, that method isn't W3C compliant.
If you put this JavaScript anywhere in your after your <body> tag then it will do exactly the same thing, only it's W3C Compliant.
Code:
<script type="text/javascript">
<!--
var message="";
///////////////////////////////////
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")
// -->
</script>
There
is a script that can be used for only disabling right click on images, however as far as I'm aware that doesn't work too well on FireFox 3.
