What looks to me as a counter-feature is that if I'm logged in to GMail, and want to stay logged-in, I have to whitelist the "google.com" cookies.

Wouldn't that allow all the Adwords tracking cookies as well, across sites?

I wonder if a better (if probably impractical approach for in a plugin) approach would be to scope off-site cookies to the containing page's domain. So an ad network's cookies on facebook.com wouldn't be shared with them on google.com. This would eliminate a lot of the "follow you around the internet" privacy issues without forcing manual configuration.

So... Blocking third party cookies?

I thought there was a big fuss about FF doing this by default or something.

Slightly different, really, though maybe in practice for a lot of current uses of it, it comes out to the same thing. Scoping, though, not blocking.

" Google uses cookies, like the PREF cookie, to help personalize ads on Google properties, like Google Search, particularly when you aren’t signed in to a Google account. We also use cookies for advertising we serve outside of Google. Our main advertising cookie is called ‘id’ and it is stored in browsers under the domain doubleclick.net. We use others with names such as _drt_, FLC, NID and exchange_uid." [1]

Wouldn't this mean that only doubleclick.net is used for advertisement tracking?
