I know at least with Do Not Track, advertising companies were asserting that if a browser had activated it by default for the user, then the user showed no intent on blocking the tracking; it was a decision made for them by the browser, and thus couldn't be interpreted as the user's wish to not be tracked. Same argument can be made about Private Browsing and Tracking Protection. Perhaps Firefox should display a "privacy start screen" the first few times the browser is launched after downloading it, explaining the features to the user, and allowing them to opt-in on their own decision? For things like DNT or Tracking Protection, I imagine most common users do not know about these things so the usage rate is much lower than it "should be". Fun fact: in Firefox you can actually turn Tracking Protection on to use it all the time, not just when you're in Private Browsing mode: Options > Privacy & Security > Tracking Protection > Always
