The Mozilla suite includes a number of tools developers can use to create their own builds of Firefox and Thunderbird. Because they’re open-source applications, any programmer can work with the code, report bugs, and get involved with the overall Mozilla organization.

Find out more about these tools and what’s due in future versions of Firefox and Thunderbird in three bonus chapters on our website: http://www.quepublishing.com/title/0789734583. On this page you can also download a glossary of new terms used throughout the book.
