Mozilla Festival is not just an annual date on the calendar. It's a collaborative community taking action on the issues that matter most all-year long.

Mozilla Festival is all about community.

We gather, online and in person to connect, collaborate, and make positive change in our digital world. From our Volunteers, to our Wranglers, to our Facilitators – we are human rights and digital activists, artists, technologists, teachers, and students with a single mission: a better, healthier, internet.

Federated Design Principals

Mozilla Festival is shared by design. Mozilla gives Wranglers driving lessons, and then hands them the keys to the car. In turn, they chart a map that Facilitators use to make the schedule come to life. Those Facilitators then take participants on a ride that inspires them to take action in their own local communities. And the Volunteers are the mechanics that ensure our adventure runs smoothly each step of the way.


These individuals seek out new and exciting directions for the festival and who will lead the festival’s Spaces and Experiences.

Data Futures Lab Showcase

The Data Future Labs (DFL) Showcase highlights local builders around the world developing data tools and platforms that prioritize the needs and interests of their communities. In the fast-paced world of AI and data the popular discourse and priorities are set by a small but vocal minority. Through the DFL Showcase we hope to highlight and support a more global outlook on Data Futures and bring together dedicated funders ready to prioritize and invest in those futures.
