    Mozilla Source Code Directory Structure


    The code for all projects in the Mozilla family (such as Firefox, Thunderbird, etc.) is combined into a single source tree. The tree contains the source code as well as the code required to build each project on supported platforms (Linux, Windows, Mac OS, etc).

    To simply take a look at the Mozilla source code, you do not need to download it. You can look at the source directly with your web browser using LXR (start at http://lxr.mozilla.org/mozilla/source/ for the complete mozilla source code of branch HEAD).

    In order to modify the source, you have to acquire it by either downloading a snapshot of the sources or by checking out the current sources from CVS.

    This document describes the directory structure that can be pulled by client.mk -- i.e., directories that are used by at least some of the Mozilla project's client products. There are other directories in the Mozilla CVS repository, such as those for Web tools and those for the Classic codebase.

    See source code directories overview for a somewhat different version of the same information.

    Files for accessibility (i.e. MSAA (Microsoft Active Accessibility), ATK (Accessibility Toolkit, used by GTK+ 2) support files). See Mozilla Accessibility.

    browser

    Contains the front end code (in XUL, Javascript, XBL, and C++) for the Firefox browser. Many of these files started off as a copy of files in xpfe/.
