Daily-driving it now. I think it's great. If you're somewhat familiar with the landscape otherwise I think readme explains how it's different and why. If you don't mind losing out on some "safety"^1^ and latest upstream features^2^ for the sake of a more stable and predictable base, not having reliance on proprietary integrations or even internet, and really removing all non-essential network integrations, then definitely worth a try!

^1^: A surprising amount of people think (or at least write online) that a browser that doesn't block user requests completely aligned with the Google SafeBrowsing blocklists is unsafe and that doing those syncs is an essential feature. If you think this is the only safe default option in 2026 I'm sorry but please consider uBlock Origin. See how opinions on who to trust can affect what "most secure" means. Konform Browser removes many assumptions of trust. But not all; Everyone still comes with an assumed PKI after all and there exists a default for DNS.

^2^: Since it's ESR base it means new feature updates from Mozilla ~yearly instead of ~monthly. Still receiving security updates on the rapid schedule. No AI features out of the box.
