gavin commented about chrome privileges in Bug 904612. We need the chrome privileges set in http://mxr.mozilla.org/mozilla-central/source/mobile/android/components/AboutRedirector.js#78 in http://mxr.mozilla.org/mozilla-central/source/mobile/android/chrome/content/aboutHealthReport.js to send messages to Java (for things like reading and setting Android shared preferences). Presumably we're exposing a chrome docshell to the remote content http://mxr.mozilla.org/mozilla-central/source/mobile/android/chrome /content/aboutHealthReport.xhtml as well. I think we should set 'mozframetype="content"' for the iframe here like you're suggesting in Bug 904612. gavin, can you verify, and suggest anything else that needs to happen?

Looks like that is a bug that exists (though I don't have an easy way to verify), and that fix should be sufficient.

Looks like I may have been wrong - see bug 856527 comment 5. I don't quite understand why, though.

Per https://bugzilla.mozilla.org/show_bug.cgi?id=1497137, this component is deprecated. Resolving this bug as incomplete, per :sdaswani.
