Mozilla is working to put control of the internet back in the hands of the people using it.
The Mozilla Project is a global community of people who believe that openness, innovation, and opportunity are key to the continued health of the internet. We have worked together since 1998 to ensure that the internet is developed in a way that benefits everyone.
Today the organizations within the Mozilla Project include: the Mozilla Foundation, which champions our mission through philanthropic risk capital; Mozilla Corporation, which makes Firefox; MZLA, which makes Thunderbird; Mozilla Ventures, which invests in responsible tech startups; Mozilla.ai, which creates open source AI developer tools; Mozilla Data Collective, a data sharing platform for human agency and fair value exchange.
Mozilla.org coordinates this whole family of organizations as well as community initiatives that support the Mozilla mission.
Mozilla is not only standing up for the open internet we originally helped to build, but also shaping what the internet is becoming in the AI era.
We're hiring across the whole Mozilla family of organizations, and looking for people who want to push the boundaries of what's possible for the internet without compromising on what matters. You'll find deep shared values and some of the best benefits in the industry.
Mozilla is a global community of volunteers, fellows and contributors who have been building, protecting and shaping the internet with us since 1998. From writing code and spotting bugs to advocating for privacy and keeping the web open for everyone, here are some ways to get involved:
