Welcome to Thunderbird

Why we need donations

You might already know that Thunderbird improvements are no longer paid for by Mozilla. Fortunately there is an active community keeping it running and developing it further. But to survive long term, the project needs funding.

Thunderbird is currently transitioning to an independent organization. Being independent, we can shape our own fate, but there is significant infrastructure that must be maintained to deliver the application to our tens of millions of users. For Thunderbird to survive and continue to evolve, we need your support and ask for your donation today. All the money donated will go directly to funding Thunderbird development and infrastructure.
