** {{bug|572149}} - JS crash in MessageManager.loadFrameScript() we need a hand debugging and fixing this. See jmaher for details.
** {{bug|572152}} - Starting last weekend, we could suddenly write to an nsIFile object from content in E10S mochitest builds. This seems wrong. Is this expected behavior?
* Fennec trunk (mobile-browser) is currently being ported to use message manager and run on either mozilla-central and electrolysis branches.
