You can configure your browsers not to accept any cookies, or not to accept 3rd party cookies. These may or may not break many sites.
Tracking more generally is not something that can be prevented by a browser which executes code written by the tracker, and must give that code access to the internet. Even if the SOP was completely enforced, trackers can still store the information on the origin server. Even if the browser doesn't expose any tracking information, the tracker can still measure all sorts of information which may be unique to your system, especially in concert with your IP address.
