For a while now, we’ve been talking about how the Do Not Track feature really has three states: “user says nothing”, “user says track”, and “user says don’t track”. In Firefox 4, we introduced two of these states with a checkbox (“user says nothing” and “user says don’t track”), and many people are voicing their desire to opt-out.
Of course, it’s reasonable to expect some people want the tracking to improve the quality of ads they see; after all, the goal of this feature is to help each individual say what they want, whether it’s pro-tracking or not.
I just finished updating the Firefox tracking preference interface to give people the ability to say, “this tracking thing is fine, bring on the custom content!” This change is still experimental, but within a day or so it will be available in our Nightly builds for testing. Take a look, let us know what you think.
