Yes, great addon. But tell me, why isn't it integrated? Why are the containers integrated, but without the option to 'always open this domain in that container'? Where's the logic in that? Why do we have to cope with having two locations of where to configure the containers? Great addon, as I said, but integrate it 100% into Firefox already. I'm sure you (as in mozilla) have lost a bunch of users of containers already because they think "Hey, that's a pretty great idea, but a somewhat unfinished implementation."
