As mentioned, each profile launches in its own window.

I use different themes for each so they are visually distinct.

And different home pages, etc.

I could use different shortcuts for different identities, but I don’t any more. Instead about:profiles is one of my home page tabs for each profile.

It also has the advantage of working the way I expect when I want to do the things I use it to do.

Do containers do that?
