On
onbeforeunload event will not work from fire fox version 26 if u used any custom alert message in your application which means you need to perform x operation when closing browser/tab or refreshing page but you put alert message in function which will be called from onbeforeunload then the x (update) operation will not happened.
<html>
<head>
<script>
function unloadfunction() {
alert('test');
// update employee ID in Database
}
</script>
</head>
<body onbeforeunload="unloadfunction();">
</body>
</html>
