Betterbird v91.9.1

A fine-tuned version of Mozilla Thunderbird, Thunderbird on steroids, if you will.

Runs on Windows, MacOs and Linux.

Betterbird is better than Thunderbird in three ways: It contains new features exclusive to Betterbird, it contains bug fixes exclusive to Betterbird and it contains fixes that Thunderbird may ship at a later stage.

Why Betterbird?

Betterbird aims at providing a better user experience by fixing annoying bugs in Thunderbird and implementing new features. We will submit all changes to upstream to eventually benefit Thunderbird. So far, Thunderbird has accepted these changes recently with more pending acceptance.

Is Betterbird for me?

If you like Thunderbird but are discouraged by too many bugs, then give Betterbird a try. It is 100% compatible with Thunderbird's ESR version. You can install the same dot release of Thunderbird in parallel and switch between Betterbird and Thunderbird on the same profile without problems and without needing the -allow-downgrade command line switch.

Will my add-ons work?

Yes, what runs in Thunderbird will run in Betterbird, you can install add-ons directly in-product from

Who is behind Betterbird?

Betterbird is headed by Thunderbird's former maintainer who has been joined by a group of people who share the view that users deserve a better experience and who do not agree with the approach of the Thunderbird management.
