Wow, thanks for such a thorough answer!

Thank you!

Explain me like I’m five - why?

EDIT: seems like there is no such thing actually, I’m confused

Didn’t know Proton Note exists lol need to check it out

Great, I hope the next step will be a desktop app since you do not always have access to the internet

I think even Facebook lets you opt out of personalized ads or is it like that only in Europe as well?

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

Well, I wasn’t really aware of the consequences it will bring (crashes, constant updates) when downloading it and didn’t want to setup regular Firefox from scratch

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’.
