I'd like to see something like the firefox container extension automatically open a new container for every unique domain name. It could get tricky for eg. federated logins, so I'm not 100% sure what the implementation would look like. But it'd be nice to have the option.

The Temporary Containers addon[1] does this. Combined with the usual Multi-Account Containers "always open this site in..." mechanism you can have some sites always open in a single container, but all other sites open in temporary containers that get deleted shortly after you close their tab.

For clarity - the workflow is basically that all sites would be temporary containers, except sites you explicitly set to be managed by Multi-Account Containers?

edit: I'm trying this out, seems to work nicely - but assigning all the sites that i want permanent state on to different account containers is a bit of a chore. Feel like i'm doing something wrong there.

But the temporary containers are working great

I don't want the containers to be transient. I want to be able to persist session cookies and local settings.

I commented on the main post, but First Party Isolation is exactly what you want, and breaks relatively few websites (and there's an extension to turn it on/off if you do use a website it breaks).
