Firefox Data Documentation

This documentation is intended to help Mozilla's developers and data scientists analyze and interpret the data gathered by the Firefox Telemetry system.

At Mozilla, our data-gathering and data-handling practices are anchored in our Data Privacy Principles and elaborated in the Mozilla Privacy Policy. You can learn more about what data Firefox collects and the choices you can make as a Firefox user in the Firefox Privacy Notice.
