window.onunload() is not working in Firefox ? works in IE?

Question

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

My JavaScript is:

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

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

Any alternative to jQuery is there?

What does `logout()` do? Does it fire a AJAX request? If so, you'll have to make it synchronous. Are you getting any errors? — Jan Hančič, Feb 04 '13 at 09:12
Thanks for your reply...Yes I am using the Ajax for logout() .It does not enter in to the **window.onunload**. — Human Being, Feb 04 '13 at 09:14
Putting alerts into the `unload` event is unreliable. Most likely your code is executing you just don't see it. Make sure your AJAX request is synchronous and tell us if it works then. — Jan Hančič, Feb 04 '13 at 09:23
@Jan Hančič I changed my ajax request to synchronous and its worked. Thank you. — Human Being, Feb 04 '13 at 09:48

Thanks for Jan Hančič.

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

And its worked well...
