I knew about FF4&5's behavior, but did not yet submit a bug or include a test case because we did not actually reach consensus on this topic yet. That, in fact, is the whole reason why we are having this discussion on fixed properties :-) Hopefully, the FixedHandler shows that the changes required to proxies to enforce non-configurability are acceptable, so that proxies can support its behavior by default.
