I disable cookies, then selectively enable them (in Firefox preferences) for sites that I choose. Sometimes it's a nuisance; citi credit cards jumps to a completely different site (cardonline.com or some such) after you log in, so the first time you do it, you just grit your teeth and cuss 'em out under your breath. Most I only allow to have session cookies.
If this tracking is something different, please let me know.

Tracking often uses a lot more data than cookies. For example see https://panopticlick.eff.org/ . User-Agent, preferred this or that, IP address, etc... even without cookies, sites can have a pretty good guess at keeping a timeline about you.
