when we mouse over a disabled button in FireFox,The title can't display.In IE ,this action is OK.
<input type='button' disabled='disabled' title='show title' value='Test'/>
As above, In IE ,when we mouse over this button ,the "show title" will display. But in firefox it can't work. Somebody can help me?it will be very appreciate.
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.
