= Introduction =
The Mozilla Platform is made-up of layers of separate technologies that go together to create various browser, Internet, and communication products. These projects all benefit from the same cross-platform, modular architecture.
= Important Platform Technologies =
== Netscape Portable Runtime (NSPR) - http://www.mozilla.org/projects/nspr/index.html ==
The Netscape Portable Runtime (NSPR) provides a platform-neutral API for system level and libc like functions. The API provides platform independence for non-GUI operating system facilities. These facilities include threads, thread synchronization, normal file and network I/O, interval timing and calendar time, basic memory management (malloc and free) and shared library linking.
Examples:

* Good example showing File I/O using NSPR -

== Gecko (Embedebale Browser Engine) - http://developer.mozilla.org/en/docs/Gecko ==
Gecko is the name of the layout engine developed by the Mozilla Foundation. It was
originally named NGLayout. Gecko's function is to read web content, such as HTML, CSS, XUL, and JavaScript, and render it on user's screen or print it. In XUL-based applications Gecko is used to render the application's user interface as well. For embeding information see http://www.mozilla.org/projects/embedding/
== XPCOM (http://www.mozilla.org/projects/xpcom/) ==
XPCOM is a cross platform component object model, similar to Microsoft COM. It has multiple language bindings, letting the XPCOM components be used and implemented in JavaScript, Java, and Python in addition to C++. Interfaces in XPCOM are defined in a dialect of IDL called XPIDL. XPCOM itself provides a set of core components and classes, e.g. file and memory management, threads, basic data structures (strings, arrays, variants), etc.
Examples of XPCOM being used:
* C++ - http://lxr.mozilla.org/seamonkey/source/toolkit/xre/nsAppRunner.cpp#2683
* JS - http://lxr.mozilla.org/seamonkey/source/toolkit/content/nsDragAndDrop.js#303
== XPConnect ==
XPConnect is a bridge between JavaScript and XPCOM. With XPConnect, you can use XPCOM components from JavaScript code, and interact with JavaScript objects from within XPCOM components.
== JavaScript==
Mozilla is the creator of Javascript, and their use of it is second to none. Many people consider JS a language for doinig simple web-page scripting. Mozilla proves that this is not the case.
Example: Adding a Bookmark in Firefox -
http://lxr.mozilla.org/seamonkey/source/browser/base/content/browser.js#1753
== XUL ==
XUL (pronounced "zool") is Mozilla's XML-based user interface language that lets you
build feature rich cross-platform applications that can run connected to or disconnected from the Internet. These applications are easily customized with alternative text, graphics, and layout so they can be readily branded or localized for various markets. Web developers already familiar with Dynamic HTML (DHTML) will learn XUL quickly and can start building applications right away.
Example XUL File (browser.xul)
http://lxr.mozilla.org/seamonkey/source/browser/base/content/browser.xul
== Extensions ==
Extensions are small add-ons that add new functionality to Mozilla applications such as Firefox and Thunderbird. They can add anything from a toolbar button to a completely new feature. They allow the application to be customized to fit the personal needs of each user if they need additional features, while keeping the applications small to download.
Modifying the Browser: AdBlock (show blocking an image from yahoo.com or Flash) https://addons.mozilla.org/firefox/1865/
Whole new Applications: ChatZilla (we'll use it later).
= Software Products Built on Mozilla =
== "Mozilla" vs. Firefox ==
Mozilla is a platform and not a browser. Many browsers (and other web-enabled applications) are built using the Mozilla platform. Firefox is the most popular and visible of these applications. However, Firefox is only a thin UI layer on-top of the Mozilla platform. Developers working in C, C++, JavaScript, HTML all work on and with the Mozilla platform.
* '''Firefox''' (http://www.mozilla.com/en-US/) -- XUL based Gecko web browser.
* '''Camino''' (http://www.caminobrowser.org/) -- A Gecko web browser that uses native Cocoa APIs for the GUI. See http://www.caminobrowser.org/images/screenshots/main_window.jpg)
* '''Thunderbird''' (http://www.mozilla.com/en-US/thunderbird/) -- XUL based Gecko email client.
* '''Eudora/Penelope''' (http://wiki.mozilla.org/Penelope_Releases) -- An email client built on-top of Thunderbird as an extension. Originally developed by Qualcomm, and now open source and run through Qualcomm/Mozilla.
* '''Sunbird''' and '''Lightening''' (http://www.mozilla.org/projects/calendar/) -- XUL based Gecko calendar clients.
* '''Miro''' (http://www.getmiro.com/) -- formerly Democracy, an Internet TV application dedicated to open standards and practices for web TV.
* '''Songbird''' (http://www.songbirdnest.com/) -- Desktop media player
* '''Open Komodo''' from ActiveState (http://www.activestate.com/openkomodo/) -- A developer tool targeting web developers and script language programmers.
