Not user-friendly despite not looking very nice. I tried selecting "alway open this site in..." "private" for addons.mozilla.org. I don't know what I am doing wrong but when I go to addons.mozilla.org it doesn't switch container. If I can't rely on this than it is useless ;(. But I love the idea (right now I am using multiple browsers)!
