Mozilla Foundation

The Mozilla Foundation is a new non-profit organization that will serve as the home for As before, will coordinate and encourage the development and testing of Mozilla code. The Mozilla Foundation will also promote the distribution and adoption of our flagship applications based on that code. AOL, Sun Microsystems, Red Hat, and other companies will continue to support Mozilla through the Foundation.

What this means for the Mozilla browser and our other products and technologies: more innovation from the open source developers, and a greater focus on end users.
