Comment 191 for bug 1022741

After a little more thought, i think it makes more sense to focus on landing this initial iframe sandbox support and handling allow-popups in a follow up, i've filed bug 766282 as this follow up. Right now, the current patch for this bug always blocks popups, so this is a 'fail closed' situation - there's just no way to opt in to allowing popups yet.

As discussed with smaug on irc, there's no automatic features tests yet because automatic features are also intended to be done in a followup, which is bug 752551.
