With Temporary Tontainers you can just install one of the cookie-ignoring plugins, since cookies don't do much if your containers are ephemeral.

It is my understanding that the name "cookie banner" is misleading, to the point of acting against your own interests.

If you click Agree you agree to be tracked regardless of the method. So yes, cookies won't do much, but now you've agreed to any kind of tracking, even those that defeat private mode and/or script blockers (assuming there's one).

I haven't really looked into the plugins but surely if they can find the "accept tracking" button, they could also find the "no thanks" button instead
