Firefox Addons Dev Guide

The Firefox add-ons developer guide was contributed by our Japan community; it covers how to go about building Firefox extensions using XPCOM and XUL. These days, we recommend using the Add-on SDK instead, but there are times when you need the additional control offered by a more direct approach.

  1. Introduction to extensions
  2. Technologies used in developing extensions
  3. Introduction to XUL—How to build a more intuitive UI
  4. Using XPCOM—Implementing advanced processes
  5. Let's build a Firefox extension
  6. Firefox extensions and XUL applications
