Bugzilla

Those of you who can reproduce this issue ... 

The developer has a test build based on nightly code (not 128) and would like feedback on whether it works or still fails. Linux, Mac and Windows:
* https://firefox-ci-tc.services.mozilla.com/api/queue/v1/task/Y5V2TooVQZqSL8eGxCop5w/runs/0/artifacts/public/build/target.tar.bz2
* https://firefox-ci-tc.services.mozilla.com/api/queue/v1/task/OdZE3YhxSl2zYsyQW9cAVg/runs/0/artifacts/public/build/target.dmg
* https://firefox-ci-tc.services.mozilla.com/api/queue/v1/task/Rkeyca4AStGtIxH_s1ZDKQ/runs/0/artifacts/public/build/install/sea/target.installer.exe

You can create a new Thunderbird data profile (which it will do by default on startup), or if you have imap accounts you should be able to use this nightly build with your current profile then go back to 128 after testing (suggest backing up first).  In most cases you are likely using a profile named xxxxx.release-default.  https://support.mozilla.org/en-US/kb/using-multiple-profiles for guidance on profiles

128.2.2 had changes to accommodate changes at google.  But a ~month of beta testing apparently was not enough - updates to 128.2.2 are no longer being offered.

If the test build doesn't work, please get the logs which you will find in Error Console - ctrl+shift+J on linux and Windows, command+shift+J on Mac.

128.2.3 which has corrections will be available by automatic update on Sept 20.  Until then you can install 128.2.1 from https://ftp.mozilla.org/pub/thunderbird/releases/128.2.1esr/win64/en-US/

128.2.2 had changes to accommodate changes at google.  Unfortunately a ~month of beta testing apparently was not enough - updates to 128.2.2 are no longer being offered.
