Thunderbird is a free and open source email, newsfeed, chat, and calendaring client, that’s easy to set up and customize. One of the core principles of Thunderbird is the use and promotion of open standards - this focus is a rejection of our world of closed platforms and services that can’t communicate with each other. We want our users to have freedom and choice in how they communicate.
Thunderbird je darmotny program wotewrjeneho žórła za e-mejl, diskusijne skupiny, bjesadu a protyku, kotryž da so lochko připrawić a přiměrić. Jedyn z jadrowych principow Thunderbird je wužiwanje a spěchowanje wotewrjenych standardow - tutón fokus je wotpokazanje našeho swěta wotzamknjenych platformow a słužbow, kotrež njemóža mjez sobu komunikować. Chcemy, zo naši wužiwarjo maja swobodu a wólbu, kak komunikuja.
