Justin Lebar f9c87527fa Bug 852847 - Part 2: Do things later in our browser-element tests, thus avoiding doing things before the browser-element machinery has loaded. r=kk1ff
Also set network.disable.ipc.security to true and leave it that way. This prevents security errors in the tests which happen when we pop the pref.
