Firefox Toolbar Tutorial

Born Geek » Firefox Toolbar Tutorial

This tutorial explains how to create a toolbar extension for the Firefox web browser (specifically for version 1.5 and later). It provides an overview of how extensions are developed, the tools required to create an extension, 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).
