As promised if I found a solid fix for the menu bug I would let you know.
It is definitely a firefox specific bug and is documented and being delt with by mozilla. See link below.

Anyway here is some javascript that fixes the issue of the browser by forcing odd width to an even width. I added it to my site and all issues are now gone!
<!-- FORCE BROWSER WIDTH TO ODD NUMBER -->
<script Language="JavaScript">
var isFireFox=new Boolean();
if (navigator.userAgent.indexOf("Firefox")!=-1) {
if (navigator.platform == "MacIntel" || navigator.platform == "MacPPC") {
isFireFox = true;
} else {
isFireFox = false;
}
} else {
isFireFox = false;
}
function isEven(value){
if (value%2 == 0)
return true;
else
return false;
}
var width;
window.onresize = function() {
if (isFireFox) {
width = window.innerWidth;
if (isEven(width)) {
self.resizeTo(width-1, window.outerHeight);
}
}
};
</script>
