Orion Browser by Kagi I’m late to the party, probably, but the Orion browser from Kagi (makers of the excellent paid search engine) is really interesting. WebKit-based, super lightweight, zero telemetry / auto ad blocking. And it supports both Firefox and Chrome browser extensions (or at least quite a few of them). Still considered beta but caught my attention for sure. The benchmarks are pretty wild.
