window.onunload（）在Firefox中不起作用？ 在IE中工作？

Question

Can anyone tell me how to fire the window.onunload event in Firefox ?

My Java Script is ,

window.onunload = function () {
        logout();
};

I need to logout the chat session when my application get closes.

Any alternative Jquery is there ?

I got the solution for onunload in firefox by changing the asynchronous in to synchronous call request.

And its worked well...
