In the early 2000s, the Mozilla community built Firefox. We toppled the browser monopoly, gave users choice and control online, and helped create a healthier internet.

Twenty years later, Mozilla continues to fight for a healthy internet — one where Big Tech is held accountable and individual users have real agency online.

Mozilla’s work is guided by the Mozilla Manifesto. Founded as a community open source project in 1998, Mozilla currently consists of two organizations: the 501(c)3 Mozilla Foundation, which leads our movement building work; and its wholly owned subsidiary, the Mozilla Corporation, which leads our market-based work. The two organizations work in close concert with each other and a global community of tens of thousands of volunteers under the single banner: Mozilla.
