Status

Thunderbird is alive and well in 2022! Please help us keep it that way!

The Thunderbird product is developed and managed by the Thunderbird Project, which is collectively the community (both paid staff and volunteers) and the Thunderbird Council:

• The community has continuously shipped releases with bug fixes and enhancements for many years. Read more at the Thunderbird Blog.
• The community holds regular meetings to discuss important matters of common interest. Meetings are open to anyone interested in Thunderbird.
• The Thunderbird Council is the governing body for the Thunderbird Project, and coordinates legal and fiscal matters on behalf of the community, and provides overall product strategy.
• The Mozilla Foundation is the project's legal and fiscal home.

Releases

Thunderbird Project version numbers for releases match to Mozilla Firefox ESR numbers. Thunderbird also provides consecutive betas between the ESR numbers, for example 92-102, which match to Firefox (non-ESR) release numbers. Future Thunderbird (ESR) releases upcoming are 103, 125, etc.

Latest release

• Get the current release of Thunderbird from thunderbird.net.
• Get the beta from the future of Thunderbird.

Upcoming releases

• Version 91 was made available in August 2021.
• Thunderbird does not release on specific scheduled dates, because we ship when code is ready and tested. But we roughly track the ESR release schedule of Firefox. See the ESR column of RapidRelease/Calendar.
  • Thunderbird ESR Releases typically happen the same week of the published Firefox dates. But it is sometimes later, because we ship when code is ready and tested. If you do not see the "newest" version listed at the Thunderbird home page, do not worry, the new version is just not yet ready.
  • New features and fixes happen as volunteers have time to work on them and fix them - fixes and features generally do not have a schedule which can be communicated to users. If you want new features sooner, then please help us test and code, or use the beta mentioned above.
