A similar idea has occurred to me. I imagine a browser plugin that allows third-party cookies, but associates them per-domain visited. That is, the cookie that google analytics gets would be different when I'm visiting siteA.com vs siteB.com.

I don't share the author's optimism that dialogue will result in "a new identity end state that works for everyone." I believe on-line privacy has to be protected through non-negotiable mechanisms, against the interests that stand to profit from taking it away.

Isn't this part of what Firefox containers do?

I think of Firefox containers (and Chrome "people") as providing a little isolation, but not enough. If I browse HN in a container, I'm likely to follow links to a lot of different domains. I'd have to diligently select the right container each time.

I'm suggesting instead the browser never mixes a cookie I was assigned while browsing say nytimes.com with a cookie assigned while browsing washingtonpost.com. Even if I regularly browse these domains in my "news" container.
