Introducing Polaris Privacy Initiative to Accelerate User-focused Privacy Online | Mozilla Privacy Blog

The second experiment (which is our first in-product Polaris experiment) seeks to understand how we can offer a feature that protects those users that want to be free from invasive tracking without penalizing advertisers and content sites that respect a user’s preferences. We’re currently testing this privacy tool in our “Nightly” channel. The experiment is promising, but it’s not a full-fledged feature yet.  We’ll test and refine the user experience and platform behavior over the coming months and collect feedback from all sides before this is added to our general release versions.
