How to detect browser event in javascript? Not working for me. Since i love mozilla to use. Working in IE.

function HandleBackFunctionality(event) {


  if(window.event)
  {
       alert("Browser1");
       if(window.event.clientX < 40 && window.event.clientY < 0)
       {
           alert("Browser back button is clicked...");
       }
       else
       {
           alert("Browser refresh button is clicked...");
       }
   }
   else
   {
        alert("Browser2");
       if(event.currentTarget.performance.navigation.type == 1)
       {
            alert("Browser refresh button is clicked...");
       }
       if(event.currentTarget.performance.navigation.type == 2)
       {
            alert("Browser back button is clicked...");
       }
   }

}

Firefox doesn't have a catch-all event object (window.event), but you can create event listeners for the objects of interest. I don't know whether the toolbar is one of those; probably not, since why should web pages be able to see what you are doing on the toolbar??

If we discard the idea of looking for events outside of the page and focus on what is happening inside the page, have you looked at this:
