Seems to be a (very old, and very abandoned) bug. See Mozilla Bugs #274626 #436770

I guess this could also be explained as intended behaviour.

One horrible Workaround that comes to mind is to overlap the button with an invisible div with a title attribute using z-index; another to somehow re-activate the button 'onmouseover' but to cleverly intercept and trash any click event on that button.
