No, your premise is wrong, all major browsers have committed to removing third-party cookies, or have already done so. And after third-party cookies, your IP address is the next-easiest way to track you across sites. that Facebook cookie works regardless of what your IP address is Firefox has been blocking third-party cookies by known trackers, including Facebook, since last year [1]. Safari started blocking all third-party cookies (not just known trackers) in March [2], and Chrome committed in January to work towards removing third-party cookies [3]. And of course, all major browsers have provided the option to block third-party cookies since before IE6. I use this option, it rarely breaks things, and it's only getting rarer—and I don't use a VPN, so this would make me measurably harder to track across sites.
