Data @ Mozilla

Who are we?

The Data team at Mozilla is made up of people with many different skills to facilitate more than just simple reporting: people who have a deep knowledge of data processing infrastructure, understanding the business and market, as well as statistical and modeling knowledge.

Vision: A sustainable, global and independent Mozilla that ethically leverages data for the common good.

Mission: We provide tools and guidance to transform Mozilla into a modern, global, ethical data-informed business.


At Mozilla, like at many other organizations, we rely on data to make product decisions. But here, unlike many other organizations, we balance our goal of collecting useful, high-quality data with our goal to give users meaningful choice and control over their own data. Our approach to data is most succinctly described by the Mozilla Privacy Principles. If you want to know what Mozilla thinks about data, the Principles will tell you that.

From those principles come Mozilla's Privacy Notices. They differ from product to product because the data each product deals with is different. If you want to know what kinds of data each Mozilla product collects and what we do with it, the Privacy Notices will tell you that.

From the Principles and the Notices we derive operational processes to allow us to make decisions about what data we can collect, store, and publish and how we go about it. Here are a few of them:

If you want to know how we ensure the data we collect, store, and publish abide by the Privacy Notices and the Principles, these processes will tell you that.
