Mozilla Open Source Support

About MOSS

Mozilla Open Source Support (MOSS) is Mozilla’s program for supporting the Open Source and Free Software movement, with a yearly budget of around $3 million. Mozilla was born out of and remains a part of this movement, and we prosper because of its technology and activism. And we know that open source software remains a key part of the Internet and is essential for the online life of choice, innovation and opportunity we seek to build.

The Mozilla Open Source Support program recognizes and celebrates open source projects that contribute to our work and the health of the Internet. It encompasses “giving back” to projects that Mozilla already relies on (“Foundational Technology”), “giving forward” to projects whose goals are in alignment with ours (“Mission Partners” and “Global Mission Partners: India”), and improving the security of the open source ecosystem (“Secure Open Source”). ”Global Mission Partners: India” is a pilot effort to focus resources on a vibrant regional open source community - in this case, in India.

MOSS is an awards program of the Mozilla Corporation, which is ultimately responsible for selecting and funding final award recipients. MOSS is administered in part by the Mozilla Foundation, the nonprofit owner of the Mozilla Corporation.

Project pillars

  • Foundational Technology

    The Foundational Technology track is open to any free software / open source project that Mozilla relies on — either embedded in our products or infrastructure, or just used to get work done.

  • Mission Partners

    The Mission Partners tracks are open to any free software / open source project that significantly furthers Mozilla’s mission to ensure the Internet is a global public resource, open and accessible to all.

  • Secure Open Source

    The Secure Open Source (“SOS”) track supports security audits for open source software projects, and remedial work to rectify the problems found.

A few details

MOSS applications are considered in batches every month. Missing a deadline may cause a delay in the consideration of your application. Information on the next deadline can be found on the MOSS wiki.

Who decides?

We have formed two selection committees to assess awards on the Foundation Technology and Mission Partners tracks. They are comprised partly of current, committed Mozillians — they bring a good working knowledge of Mozilla’s day- to-day activities and how various open source projects are used. There are also senior Mozilla Alumni — they are no longer actively involved with Mozilla on a day-to-day basis but have a deep understanding of our project and a different/outside perspective. Finally, there are other open source experts — they bring knowledge of the role of different projects within the open source ecosystem.
