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.
