This sounds better than my current solution of multiple Chrome profiles, but how does this interact with extensions? So many extensions require broad permissions that give them nearly as much power as the browser vendor themselves. With separate Chrome profiles, I can keep sketchy extensions away from sensitive credentials. I hope these containers do something similar, because I think the UX of per-tab containers might be superior to per-window profiles.
