The Mozilla Foundation (stylized as moz://a) is an American non-profit organization that exists to support and collectively lead the open source Mozilla project. Founded in July 2003, the organization sets the policies that govern development, operates key infrastructure and controls Mozilla trademarks and copyrights. It owns two taxable subsidiaries: the Mozilla Corporation, which employs many Mozilla developers and coordinates releases of the Mozilla Firefox web browser, and MZLA Technologies Corporation, which employs developers to work on the Mozilla Thunderbird email client and coordinate its releases. The Mozilla Foundation was founded by the Netscape-affiliated Mozilla Organization. The organization is currently based in the Silicon Valley city of Mountain View, California, United States.

The Mozilla Foundation describes itself as "a non-profit organization that promotes openness, innovation and participation on the Internet".^[2] The Mozilla Foundation is guided by the Mozilla Manifesto, which lists 10 principles which Mozilla believes "are critical for the Internet to continue to benefit the public good as well as commercial aspects of life".^[3]
