A lot of companies say they’re “mission-driven”. Our unique corporate structure guarantees that every decision we make upholds our mission: to make sure the internet stays available, safe, and welcoming to everyone. Beholden to neither shareholders nor investors, Mozilla Corporation is wholly owned by the not-for-profit Mozilla Foundation.
Along with 20,000+ volunteer contributors and collaborators all over the world, Mozilla Corporation’s staff designs, builds, and distributes software that allows people to enjoy the internet on their own terms. Our flagship product — the Firefox browser — has expanded into a family of products that protects users and alerts them of risks.
Have you ever wanted to make automation prevent regressions that would affect millions of users? At Mozilla, we run millions of Firefox tests for each commit to our master branch!
Our team takes these tests under their care by running them on modern operating systems, ensuring tools are up to date and have scalability, all while keeping an eye on the budget.
We also work with developers (our users) to set their new tests up at scale and ensure they are aware of what tests are providing value (identifying regressions) and hiding noise (flaky failures).
Last but not least, we maintain the harnesses that Firefox developers use every day to write and run their tests.
