Plug-in Basics - MDC
How Plug-ins are used Plug-ins offer a rich variety of features that can increase the flexibility of Gecko -based browsers. Plug-ins like these are now available: The range of possibilities for using plug-in technology seems boundless, as shown by the growing numbers of independent software vendors who are creating new and innovative plug-ins. You can see which plug-ins are installed on your system and have been properly associated with the browser by consulting the Installed Plug-ins page.Drawing and Event Handling - MDC
This chapter tells how to determine whether a plug-in instance is windowed or windowless, how to draw and redraw plug-ins, and how to handle plug-in events. When it comes to determining the way a plug-in instance appears in a web page, you (and the web page author) have many options. The content provider who writes the web page determines its display mode : whether the plug-in is embedded, or displayed in its own separate page.

Canvas c1 is used to display the current frame of the original video, while c2 is used to display the video after performing the chroma-keying effect; c2 is preloaded with the still image that will be used to replace the green background in the video. The JavaScript code is imported from a script named main.js ; this script uses JavaScript 1.8 features, so that version is specified in line 22 when importing the script. The doLoad() method is called when the XHTML document initially loads.
Using audio and video in Firefox - MDC
