The Mozilla Corporation is wholly owned by the non-profit 501(c) Mozilla Foundation. This means we aren’t beholden to any shareholders — only to our mission. Along with thousands of volunteer contributors and collaborators all over the world, Mozillians design, build and distribute open-source software that enables people to enjoy the internet on their terms.

About this team and role:

Our team is geographically-distributed, and working in the open is the norm. We contribute to the code driving Firefox on a number of desktop platforms - Windows, Linux, and macOS.
