I only wish it was more automated. Every site should automatically get its own container.
How much of the anti-tracking value is defeated by non-cookie browser fingerprinting?
So FB gets a different container. Google accounts get a container each. When I need to log in with Google - use the Google account's container.
Work gets different ones - depending on nature of work.
That makes it easy to manage containers for me.
In theory that account's data tracking to an extent is limited. But with browser fingerprinting I doubt this whole set up is very useful once you start aggregating data from multiple providers.
This will break almost all sso when authentication service is at different domain.
