In my experience that had better support for per-eTLD temporary containers, so that each site can have its own, and the data can be discarded relatively soon. I also have more permanent containers for things that I want to be able to persist (e.g. work uses SSO so I need to link multiple sites together to log in).
When I used it I found the management in Multi-Account Containers to be onerous (I don't believe it could do automatic containers based on eTLD).
Oh wow, okay this makes things a little easier. I've always struggled with logging in as the SSO-flow has domains that I haven't added to the "Always open in X tab". Hopefully the functionality gets incorporated into the MAC addon eventually!
.. I say hopefully, man I feel guilty getting so much use out of these addons when I could be actively contributing. Fuck it, donating.. https://donate.mozilla.org/en-US/
This is going to take care of my biggest gripe with Multi-Account Containers; it leaks cookies to the default container if you open the site management list because it looks up favicons each time. I just tested Containerise and multi-container cookie jars, it does not leak cookies with this.
Finally, painless container management!
