Loading remote web content in the parent process is dangerous in a post-sandbox world, as it means loading remote content outside the sandbox. About:addons loads remote content, mainly from our own sites, but also remote sites like google analytics. From what i have seen so far, all connections seem to be SSL, so that it a mitigating factor, but we should consider moving this to a content process (either existing or new).

PS Couldn't find a more specific component, please move as appropriate.

This should be fairly trivial, ie setting remote=true on the <browser> we use to frame the discovery pane. Dave, do you or Andrew have cycles for this?

I seem to recall that it isn't quite that simple but I'll take a look and see what the state is.

Mossop and I discussed a Gecko bug that he was hitting about this today.  I'll file it tomorrow.

WIP patch

This is the WIP, really only the change to extensions.xul is necessary and the exception happens when you open the add-ons manager UI.

Not sure which patch you are asking for.  The fix will be in bug 1340747.

Dave, Michael posted a patch in bug 1340747 which I just r+ed.  That should unblock you here.  Let me know if you run into any other issues.
