The custom message is ignored, no matter how it is returned, both via event.returnValue and via return 'message' method of the function itself. Reproducible: Always Steps to Reproduce: 1. Assign an event handler to window.onbeforeunload event 2. In the event handler function, use both event.returnValue and return method to include a custom message beside the default message. Actual Results: Only the default message is shown. Internet Explorer and Google Chrome display correctly. Expected Results: The custom message should be displayed along with the default message.
AFAIK, This is by design, see Bug 588292
