Governance

Overview

To add, remove, or update module information, see the mots documentation.

Thunderbird operates under Mozilla’s module ownership governance system. A module is a discrete unit of code or activity. An owner is the person in charge of a module or sub-module. A peer is a person whom the owner has appointed to help them. A module may have multiple peers and, very occasionally, multiple owners.

The system is overseen by the owner and peers of the Module Ownership module. For the modules that make up Thunderbird, oversight is provided by the Thunderbird Council module. Owners may add and remove peers from their modules as they wish, without reference to anyone else.

Modules

Thunderbird Council - 2023

The Thunderbird Council is the elected governing body for the Thunderbird Project, including the code modules that develop the code in Thunderbird product(s). It is the top-level module of the project, and Peers are members of the Council.
