The issue of course is that at the moment, cookies are cookies. There's already the ability to disallow 3rd party cookies but you would still lose functionality.<p>My solution to this would be different cookie silos. There is already a "private browsing" feature in modern browsers - why not having multiple personas?<p>I use this silo when I'm working, this one when I'm shopping, this one when I'm looking up midget porn etc.<p>As well as "open in new tab" links would have "open with new persona" so that if you were on your facebook page and you wanted to go look at a site about testicular cancer you could do so with privacy.<p>You should then be able to reload the current page using a different persona so that you can decide how to engage with the page you're currently looking at.
