Wait ... is Thunderbird not a Mozilla project but its own entity?
As of today, the Thunderbird project will be operating from a new wholly owned subsidiary of the Mozilla Foundation, MZLA Technologies Corporation. This move has been in the works for a while as Thunderbird has grown in donations, staff, and aspirations. This will not impact Thunderbird’s day-to-day activities or mission: Thunderbird will still remain free and open source, with the same release schedule and people driving the project.
