Version history of Mozilla Thunderbird

from Wikipedia, the free encyclopedia
Mozilla Thunderbird 38.3.0 on Windows 10

Mozilla Thunderbird , the free e-mail program of the Mozilla project, is based on the source code of the Mozilla Suite . It was released under the name Minotaur shortly after Phoenix (the original name of Mozilla Firefox ) was released. With the success of Mozilla Firefox and the migration to the new Firefox toolkit, the program then became successful under the name Thunderbird .

Timetable

The diagram shows the individual versions of Mozilla Thunderbird arranged according to their release on a time table and is intended to provide an overview. Some release dates have been postponed to avoid conflicts with holidays. Similar to the development at Firefox, a beta version of Thunderbird is regularly available before the release of new versions, which takes over the error corrections and, if necessary, new features from the web browser.
