Question: ```
$(window).bind("beforeunload",function(){
    return "cant be seen in ff";
});

```

The problem is that i can't see the "cant be seen in ff" on the confirm box in my FireFox browser, but works well in other browsers(IE Chrome)

Any solutions??

Answer: 
See this: <https://bugzilla.mozilla.org/show_bug.cgi?id=588292>

It looks like forefox decided to remove the support for the beforeunload as we know it.
do this 

```
<script>
    window.onbeforeunload = function(){
         return "cant be seen in ff";
    }
</script>

```
