Tried containers when it was released but found it very inconvenient to manage. If I understand this solution doesn't even let you have two profiles open at once? That's even less useful imho.

edit: I use Simple Tab Groups which is far more featureful - "Send tab to [group/container/etc]" for example is table stakes.

Of course you can have them open at once, that's what's useful. I have four! And I can open subsequent windows in the right profile, no problem. But it required non-trivial scripting.

I personnally went for extensions using them. I downloaded, Google, Facebook, Amazon, Youtube containers extensions.

I have had issues with Youtube and Google together. I think I solved it using the "Don't track me Google extension" but I am not so sure anymore
