This dialog looks like chrome, and chrome removed the option to customize this message, see here: https://developers.google.com/web/updates/2016/04/chrome-51-deprecations?hl=en#remove_custom_messages_in_onbeforeunload_dialogs

Also this answer claims it's not only chrome, but most browsers https://stackoverflow.com/a/38880926/299774
