Summary: onbeforeun Does Not Use Embedded Text On Return → onbeforeunload Does Not Use Embedded Text On Return
It seems Facebook shows a message properly on firefox. To reproduce go to your facebook page (if you have one) then type something on the status box. now try to navigate away from the page and it shows a custom message. Anyone know how they do this?
