Remove cookies from the HTTP specification, and more importantly, browsers. Replace it with a single "session token" value that you are allowed to set. Can only be created in response to a form post. No cross domain. Make all the other web API stuff an smartphone-style opt in. "This app requires the following permissions: "Store private data in your browser. Only do this for site you trust as this can be used to track you." etc. Maybe all the above can be made into an extension as a stop gap.
