Freedom

Voice

You have a part in Thunderbird's future.

Thunderbird is free from the commercial requirements and incentives that often guide software development. Anyone can get involved in helping make Thunderbird better and available to more people. A contributor-elected council ensures Thunderbird remains true to its values and mission.

Driven by Community

Anyone can help make Thunderbird better. Programmers can contribute features they are passionate about or improve the existing code. Those who are multilingual can make Thunderbird accessible to everyone. Those willing can test new versions of Thunderbird and document issues. There are many ways to become part of a thriving community that makes Thunderbird unique. And if you don't have the time to volunteer, you can help support our work with a financial contribution.
