To get started creating the most basic extension framework, please see Building a Thunderbird Extension.

This page is organized into two parts: common extension techniques and Thunderbird-specific APIs. The former discusses general methods to hook into Thunderbird, while the latter is more focused on how to do interesting things once Thunderbird has started running your code.

See also "An overview of Thunderbird components". Many of the components described on that page have links to related examples.
