title: FireFox handling of disabled fields
body: <p>I have an HTML form with a select list and a radio button, both of which are initially set with disabled = true.  At some point, these elements are enabled via JavaScript (i.e., disabled = false).  This works fine in IE and Chrome, but in FireFox the element remains disabled.  It appears to be enabled, but doesn't respond to mouse clicks.  When I inspect one of the elements using FireBug, the disabled attribute is false.  Are there known issues with FireFox when dealing with form elements that are initially disabled, then enabled?</p>
  
  <p>Thanks.</p>
