Textual words from them:
It’s our first step towards a more modern, more beautiful, and more customizable Thunderbird experience. We think you’re going to love it, and we are endlessly grateful for all of your support throughout the years 💙
Oh no! It looks like an electron app.
Can anyone confirm whether or not it’s built on Electron?
The closest I can find is from Feb 2023, saying that at that time it would not be Electron:
Mozilla also still plans to use the Firefox web browser as the core platform for Thunderbird. That leaves Thunderbird as one of the few cross-platform mail applications that isn’t an Electron app or based on web technologies in some way
So possibly Electron-like but based on Firefox rather than Chromium?
It’s based on the “Mozilla application framework” [0]

It’s not an electron app, I installed it.
Is it one though? I’m having a difficult time finding the source code of this new version.
