Mozilla Foundation

Mozilla Foundation is a non-profit building a better technology future — powered by people, open by design, fueled by imagination.

We deliver people-first alternatives to today’s extractive systems. We build side by side with developers, innovators and advocates, united in the belief that a better technology future is not only possible — it’s ours to create.
