What can i do to get this value?

function getScrollSizes() { // call after document is finished loading
    var el= document.createElement('div');
    el.style.visibility= 'hidden';
    el.style.overflow= 'scroll';
    document.body.appendChild(el);
    var w= el.offsetWidth-el.clientWidth;
    var h= el.offsetHeight-el.clientHeight;
    document.body.removeChild(el);
    return new Array(w, h);
}

And is the height the same in FireFox and Internet Explorer?

No. The height isn't even the same in Internet Explorer and Internet Explorer. Variables such as dpi settings, theme and OS version can also affect it.
