Ending a session on browser close only (firefox)

Question

I'm trying to end a user's session when they close the browser, because they never logout properly.
I need to change a value in the db after they close the browser only.
<script type ="text/javascript" >
var clicked = false;
var xmlHttp
var browser = navigator.appName;
function CheckBrowser() {
if (clicked == false) {
xmlHttp = GetXmlHttpObject();
xmlHttp.open("GET", "../LogOut.aspx", true);
xmlHttp.onreadystatechange = function () {
if (xmlHttp.readyState == 4) {
//alert(xmlhttp.responseText)
xmlHttp.send(null)
if (browser == "Netscape")
alert("Nog een fijne dag.");
else {
//alert("Redirected");
clicked = false;
function GetXmlHttpObject() {
var xmlHttp = null;
try {
// Firefox, Opera 8.0+, Safari
xmlHttp = new XMLHttpRequest();
catch (e) {
//Internet Explorer
try {
xmlHttp = new ActiveXObject("Msxml2.XMLHTTP");
catch (e) {
xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
return xmlHttp;
</script>
That works for every browser except firefox.
Please help me with this.
