Thunderbird Turns 20, Thanks to You!

20 Years

On December 7, 2004, Thunderbird 1.0 was released.

Thunderbird is free. Free to use. Free of ads. Free of data tracking.

We rely solely on the generosity of our supporters and less than 3% of Thunderbird users keep us going.

Please help us continue for another 20 years.
