Handle the beforeUnload event.

Assuming you use jQuery:

$(window).on("beforeunload", function() { 
        return confirm("Do you really want to close?") 
    }
);

Thank you for the answer.

I tried it and it doesn't work in firefox.

The MDN documentation for the event says:

Note: To combat unwanted pop-ups, browsers may not display prompts created in beforeunload event handlers unless the page has been interacted with, or even not at all.

Also:

Various browsers ignore the result of the event and do not ask the user for confirmation at all. The document will always be unloaded automatically. Firefox has a switch named dom.disable_beforeunload in about:config to enable this behaviour.
