I need fine grained, automated cookie controls I have tried these addons

Cookie Manager Cookie Quick Manager Cookie AutoDelete

And the problem is always the same.

It is TOO DIFFICULT to only have one exception for one cookie in one account container

Creating containers for every single website is also extremely tedious and buggy.

And deleting all cookies all the time, means I am re-logging in into everything all the time, often a 5 to 10 step process not counting 2 factor and it is VERY annoying

Yes, and also on a per-container basis, because different containers have different logins to the same website As I described in the other post https://lemmy.ml/post/30131984/18621605

I think you are correct to say it is currently impossible.

Well according to chatgpt, because

Cookie AutoDelete can whitelist by domain, but not per-container.

Firefox Multi-Account Containers (MAC) don’t expose cookie APIs per container to extensions — this is a Mozilla limitation.

Session cookies (those not marked as persistent) are deleted on shutdown unless the domain is explicitly allowed to "stay logged in" (via about:preferences#privacy > Cookies & Site Data > Exceptions). But not on a per-container nor per-cookie basis, it is all or nothing. Whitelisted websites keep ALL their cookies

Lastly, there does not exist a repository of cookie rules for user to share the session cookie names on a per-website basis

In other words, there does not exist a "sponsorblock-like" equivalent but tracking and identifying in a crowdsources way, the session cookies
