Thunderbird 138.0.2 fixes:

https://www.thunderbird.net/en-US/thunderbird/138.0.2/releasenotes/

What is fixed:
“It’s basically a complete redesign of how you add accounts (like email, calendars, etc.) in Thunderbird. The old setup system worked, but it looked a bit dated, could be confusing with its tab-based approach (easy to accidentally close!), and wasn’t very consistent across different account types.
The Account Hub aims to fix all that. It provides a single, unified, modern-looking wizard inside a pop-up window (modal) to guide you through setup. For brand new users, this modal will guide them without letting them get lost before their first account is ready.”

The whole building process lasted approximately 8 minutes on my AMD Ryzen 9 7950X3D 16-Core Processor and required 30.1 GiB (32,355,790,419), 1,401,719 files, 138,437 sub-folders

“On December 7, 2004, Thunderbird 1.0 was released.”

Will introduce Mozilla Sync in a later minor release.
“The client code is finished, everything is in place and we’re testing syncing server data against a temporary staging server. We’re still working on spawning our own production server, which turned out more challenging than expected.
This means that potentially we won’t enable Sync by default for the first ESR release and instead keep it hidden temporarily, with the objective of enabling it in a future point release (maybe 128.1 or 128.2) depending on when the production server will be ready.”

We live in 2024 and Thunderbird still does NOT support RSS notifications and a tray icon natively. I am simply annoyed, frustrated and pissed…
