Wow, thanks for such a thorough answer!

Thank you!

Explain me like I’m five - why?

Mine is still updating from aurora channel 😕 I’m on v118.0b2 now. Guess it didn’t really work

no :/

This is exactly what I wanted, thanks a lot!

I would wait and see if channel gets updated after next update

Alright, I figured it out myself - you need to change app.update.channel in about:config to release. TIL that developer edition has its own update channel called ‘aurora’ which is even more experimental than ‘beta’.
