Firefox Project

Firefox is created by thousands of people around the world working together to build a better Internet. If you're already a member of the community, thank you for everything you've done. If you're new to Mozilla, feel free to get involved—you don’t have to be a C++ guru (or even know what that means!) to contribute.
