Add-on SDK
Publisher's Description
From Mozilla Labs:
The Add-on SDK provides powerful APIs and tools that allow developers to create add-ons for Firefox using HTML, CSS and JavaScript. When your add-on is complete, we make it easy to share it with over 400 million Firefox users world wide.
The Add-on SDK is set of APIs bundled with a command line utility that allows you to develop add-ons with your own tool chain.
