Firefox Toolbar Tutorial

This tutorial explains how to create a toolbar extension for Firefox. It provides an overview of how extensions are developed, the tools required to create them, and details on how toolbars are created. Please note that this tutorial is lengthy; I recommend spending time with it over the course of a few days (it makes for a good weekend read).

Extension development isn’t difficult, though some basic programming knowledge is required. There are three basic areas you should be somewhat familiar with: XML, JavaScript, and CSS. None of these topics are difficult to pick up, and there are a number of excellent tutorials on each around the web (I will highlight some as we continue).
