General information


How YOU can help and get involved ... Thunderbird is self-supported by its user community. We need and welcome you. Please give back to the community.

To get more information or talk to a human, or just to introduce yourself, see Thunderbird Communication Channels, especially the IRC channel. Again, we need users like you to help in one of the above areas. Please inquire today.


Thunderbird's release schedule tracks, but does not strictly follow**, the ESR release schedule of Firefox. See the Firefox schedule (with an ESR column), at RapidRelease/Calendar.

'** Releases ship when the Thunderbird code is ready based on testing and other factors, not on a specific date certain. So take any dates you see with a grain of salt - because we will lag by some days or weeks, not ship by a published date. Not seeing the "newest" version at the Thunderbird home page? Do not worry, it is just not yet ready for release.

Latest release

Upcoming releases

Thunderbird gets new features and bug fixes as volunteers have time to work on them and fix them. There are no schedules for features or specific fixes that can be communicated to users. If you want new features sooner than normal, use the beta mentioned above.
