@nprofile1q... If you're in the US, the best way to donate anonymously is via mailing a money order for now (https://www.thunderbird.net/donate/#faq) and to suggest easier, more anonymous methods here on Connect: https://connect.mozilla.org/t5/ideas/stop-requiring-donors-to-provide-extra-information/idi-p/47075 - and even if you're not able to give now, we appreciate you being part of the community!
