Build ID: 20141023030203

Steps to reproduce:

Start Firefox without extensions.


Actual results:

mutating the [[Prototype]] of an object will cause your code to run very slowly; instead create the object with the correct initial [[Prototype]] value using Object.create Preferences.jsm:378


Expected results:

No warning.
