The Mozilla Foundation describes itself as "a non-profit organization dedicated to preserving choice and promoting innovation on the Internet". Mozilla Europe, Mozilla Japan and Mozilla China are non-profit organizations whose mission is to help promote and deploy Mozilla products and projects. They are independent of, but affiliated with, the Mozilla Foundation.
On August 3, 2005, the Mozilla Foundation launched a wholly owned subsidiary called the Mozilla Corporation to continue the development and delivery of Mozilla Firefox and Mozilla Thunderbird. The Mozilla Corporation takes responsibility for release planning, marketing and a range of distribution-related activities. It also handles relationships with businesses, many of which generate income. Unlike the Mozilla Foundation, the Mozilla Corporation is a taxable entity, which gives it much greater freedom in the revenue and business activities it can pursue.
