I use it to log in two or more Google accounts in different containers while still being able to search anonymously in a default tab when needed. This is really great !

It would be even better if the menu allowed to open a standard default tab in addition to container tabs, though it is still possible by pressing Ctrl+T.

There is countless great things you can do with Multi-Account Containers to control your privacy and use multiple identities in the same time. It even helps you to keep your tabs organized.

I highly recommend it if you like to keep many tabs open.
