snowee and lf-araujo I explored Zen since it gets a lot of lip service. It's as pretty as Floorp that is for sure and gimmicky with creative tabs/colors etc. Real easy on the eyes like Floorp. Like Floorp, security is not really their concern, like Firefox. Not a word I could find in their Github or Zen page about it but like I said not a whole lot of time.
Vivaldi is to Chrome as Zen is to Firefox, imho: a prettier version of the same thing.
Ungoogled is fine for me. Brave sometimes as far as chromium variants.
But you are talking about Zen and FF.
These days it's just OOTB LibreWolf and Mullvad browsers for me as far as FF derivatives. Most of the dirty work of the internet is clamped down by them and neither ever broke anything.
experience and observation still make this 2 cents
