I don’t need more than the basics, things like hardware acceleration and extension support, although websql and the likes are occasionally useful. I don’t sync, I don’t need pocket or a vpn, and mozilla telemetry has caused my laptop to almost be rate limited by my pihole before. Ungoogled chromium does exactly what I need it to do while feeling faster than firefox. Idk if it actually is, but sometimes feelings are enough. And with the market share of chromiums engine, I don’t think the potential fingerprinting of its features is statistically relevant.
