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.

12569342da Bug 852847 - Part 1: Disable browserElement_oop_KeyEvents.html. r=kk1ff
In fact this test was already disabled; the OOP version was the same as
the in-process version because the test explicitly disabled OOP tabs.

bd3e5c86b6 Bug 842476: Work around leak resulting from exception that happens during unload by propagating only the prompts we expect and not the later ones. r=jlebar
Make this test less sensitive to the timing of its own unloading by
passing on only the expected messages and not any messages that occur
during unloading.  Such messages might cause exceptions (e.g.,
"'TypeError: can't access dead object' when calling method:
[nsIPrompt::alert]"), and those exceptions might in turn trigger leaks
in nsXPConnect that last until shutdown because we store the most recent
exception from a call to an XPCWrappedJS on the XPCJSRuntime through
shutdown (rather than reporting it, as we probably should, and then
freeing it), leaking the window.

642ac8b6e8 Bug 844530 - Paper over error in BrowserElementPromptService.jsm on B2G. r=khuey
The error we're fixing is

  E/GeckoConsole(  397): [JavaScript Error: "NS_ERROR_FACTORY_NOT_REGISTERED: Component returned failure code: 0x80040154 (NS_ERROR_FACTORY_NOT_REGISTERED)
  [nsIComponentManager.getClassObject]" {file: "resource://gre/modules/BrowserElementPromptService.jsm" line: 572}]

For some reason, we're running code before the vanilla prompt service is
instantiated.  We don't know why this is happening, but this patch works
around the problem on B2G, which is the only place where we ship this
code.
