Mozilla is a global organization dedicated to an open and accessible internet. Established as an open-source community project in 1998, Mozilla's mission is guided by the principles of the Mozilla Manifesto, emphasizing the internet as a global public resource. It operates through two entities: the nonprofit Mozilla Foundation, which is focused on advocacy and building a healthier internet, and its commercial arm, Mozilla Corporation, which develops products like the Firefox browser.

Mozilla promotes internet health by advocating for user choice, privacy, and accountability of big tech companies. It also invests in research and initiatives such as Common Voice, an open dataset for voice technology, and the Mozilla Festival, which connects global communities working toward ethical tech solutions.
