Betterbird: Downloads

Future version: Betterbird 115.2.3-bb12 "Superstar" (19 September 2023)

All binaries, installers, etc. have been replaced on 20 September 2023 to mitigate a severe startup performance regression related to unified folders. If you are in doubt which version you have, consult the Build ID in Help > Troubleshooting Information.

Note that Thunderbird 115 is still very much work-in-progress with features destined for version 115 still incomplete and various "Supernova" bugs not fixed in the current version.
