Another option is to always delete cookies and site data when you close Firefox and set exceptions for the few sites you care about. If you are like me and only start Firefox once or twice a day this prevents too much annoyance while limiting cookie based tracking. Also, Mozilla should really think about what is wrong with the statement "Since we enabled ETP by default, we’ve blocked 3.4 trillion tracking cookies." I imagine most people who care about tracking would like to not be tracked by anyone, not just anyone other than Mozilla.
