The Mozilla Foundation is a non-profit organization that exists to support and provide leadership for the open source Mozilla project. The organization sets the policies that govern development, operates key infrastructure and controls trademarks and other intellectual property. It owns two taxable for-profit subsidiaries: the Mozilla Corporation, which employs several Mozilla developers and coordinates releases of the Mozilla Firefox web browser, and Mozilla Messaging, Inc., which primarily develops the Mozilla Thunderbird email client.
