Answer 1

"refresh" action in the Firefox does not fire the unload event.

We should use onbeforeunload instead.

This should work to show a confirmation when the users leaves, this is also not part of any standard.

$(window).on('beforeunload ',function() {
    return 'Are you sure ?';
});

Answer 5

I found Joseph's comment as the correct answer, So posting this answer.

Dialogs are blocked/prevented during "beforeunload" (with exception to the beforeunload prompt) and "unload" events. Can be confirmed by checking your console.

Answer 6

you can use onfocusout on the body .. but i wouldn't recommend if you are trying to use something like an alert, on this operation, asking the user not to leave your page ..
