Konform Browser is more recent Firefox (actually LibreWolf) fork which goes even further in debloating, removing "AI" functionality and disabling remote connections. It's based on Firefox ESR (like GNUZilla IceCat).
If you have concerns about the telemetry and browser metadata privacy parts of AI integrations, I think Konform, IceCat, Waterfox and Mullvad Browser are a lot more relevant than Zen...
Grumpy ken thinks "Just use Foo" meming is promoting mindless use and I think should therefore be discouraged. Even in jest I think this affects us subconsciously to feel more comfortable with not thinking deeper for ourselves. Even if X is the right one. "Use Foo already!" is nicer~!
If I may illustrate:
Use Konform Browser^1^ already!
