There was an issue with Zen about a year ago, it used to send Mozilla telemetry requests, and the developers had ignored any complaints on it. Anyone knows if the situation has changed since?
I found nothing on how private Helium is. People usually just say it is garbage because of the engine, but that’s not what I care about.
I’ve been using both, helium mainly for sites that needs webgl (mostly my self hosted stack) and jellyfin, Grimmory, and zen for docs, dev tools and things that requires login like codegerg, kagi, OSM etc, and also got librewolf for everything else
