I’ve used Thunderbird off and on for years, but with my move to Fedora fulltime just over a year ago Thunderbird is again my main email client. During that year I was asked to donate when I downloaded the client, and again today on their 20th Anniversary.

I donated both times and wouldn’t mind a reminder every few months to donate to keep a project I use regularly going. Even open source software takes money to keep development going and I’m happy to contribute to the projects I use.
