Agreed, containers are great. I love them and wish they were a standard feature across browsers. Still some room for improvement though. It would be nice if the containers acted like an entirely different instance of a browser, with different settings, history, extensions, etc. With the current design it's still possible to accidently leaked details across containers by visiting something in the wrong one if you havent set up exclusive browsing for a particular site, and history is shared across containers. Would be nice to be able to export container settings as well as a lot of work can go into setting them up.
