Unfortunately this is another case of throwing the baby out with the bathwater, and incidentally not really solving the problem.<p>Firstly there are various kinds of cookies. There are ones that are stored on your hard-disk, and others which exist only in memory (for the life of the browser instance.)<p>There are ones used for marketing and tracking purposes, and others (notably session cookies) that allow the server to track the "state" - thus allowing for "web apps" as much as web-pages.<p>So their idea is to just "ban cookies". Or, as they have done, get all sites to have a "allow cookies" switch. Don't turn that on? well then you can't use any part of the site.
And if you do turn it on, it's "all or nothing" - I can't allow say _just_ the session cookie, while banning the tracking cookies?<p>As to the possibility of enforcing this? Let's not even go there...
