From bug 1382635: As already mentioned by Ehsan in bug 1373672 comment #0, the FormDataListener listens for both change and input events, based on a decision made long before we imported the add-on code into Firefox. AFAICT whenever the user interacts with a form element we dispatch the "input" event properly, I couldn't find a counterexample. In the past (Firefox 2 and before) we might have had inconsistent behavior.
A patch which actually applies to the current trees and not only to 2.53
