Adding an attribute to an existing element currently seems impossible unless I am really missing something. Say you have.. <div> In any other tools you can double click it and press tab to add an attribute. Most have a right click option to edit as well. With firefox this simple task isn't possible. So adding a class to the above element requires you to at least add class="" to the element...
