Catch the event on closing window using mozilla browser

Hi

I tried the following code to catch the event on closing window.I am taking the unloadevent. But its not working in mozilla and working in IE browser.

function onBeforeUnloadAction()
{
var flag=window.confirm("You are closing the window. do you want to continue. Click 'Ok' to close or click 'Cancel' to stay back");

if(flag)
{
alert("bye");
}
else
{
// Stop the closing browser
//....
}
}
function fun()
{

if((window.event.clientX<0) || (window.event.clientY<0))
{
onBeforeUnloadAction();
}
Please give the solution to this one.
