Comment(by mikeperry):

 Damnit. You're right. It looks like Firefox totally missed the point of
 these new ES5 features by allowing Components.lookupMethod to bypass them.
 I wonder when this changed. It totally seems like Heiderich was planning
 on relying on the fact that Components.lookupMethod could not bypass these
 protections. There goes his thrown room...

 Also, to make things extra fun, you cannot override
 Components.lookupMethod itself, as it is set as non-configurable!

 I suppose we can just make Components.lookupMethod configurable in our
 fork of Firefox, and then use this to remove it. We also want to remove
 Components.interfaces, because all that does is let you fingerprint which
 Firefox version you have. But guess what: Components.interfaces is also
 not configurable..
