Contributions go to the Mozilla Foundation, a 501(c)(3) organization based in Mountain View, California, to support Thunderbird. Mozilla reserves the right to find another use for the funds if it determines that Thunderbird is no longer furthering Mozilla’s mission. They are tax-deductible in the U.S. to the fullest extent permitted by law.
