As Do Not Track picks up steam and standardization is well underway in the W3C, people have begun asking, “If Do Not Track is so good for the web, why don’t you turn it on by default?”
Frankly, it becomes meaningless if we enable it by default for all our users. Do Not Track is intended to express an individual’s choice, or preference, to not be tracked. It’s important that the signal represents a choice made by the person behind the keyboard and not the software maker, because ultimately it’s not Firefox being tracked, it’s the user.
Mozilla’s mission is to give users this choice and control over their browsing experience. We won’t turn on Do Not Track by default because then it would be Mozilla making the choice, not the individual. Since this is a choice for the user to make, we cannot send the signal automatically but will empower them with the tools they need to do it.
Do Not Track is not Mozilla’s position on tracking, it’s the individual’s — and that’s what makes it great! For that reason we have no plans to turn on Do Not Track by default.
