The mozilla-central repostitory contains the Firefox codebase and all of the platform code. Check out our Getting Started documentation for instructions on how and where to get the source code.

In order to be able to build Thunderbird - you will need the mozilla-central repository as well as the comm-central repository (where this README lives). As such the two projects share a lot of code and much of the documentation for one will apply, in many ways, to the other. Thunderbird is built on the Mozilla platform, the same base that Firefox is built from. This README will try and give you the basics that you need to get started, more comprehensive documentation is available on the Thunderbird Developer Website. It is based on the same platform that Firefox uses.

Thunderbird is a powerful and customizable open source email client with lots of users.
