Librewolf is a fork of Firefox.

From their site:

LibreWolf also aims to remove all the telemetry, data collection and annoyances, as well as disabling anti-freedom features like DRM.

In the future, Ladybird or a browser built on top of Servo might be alternatives, but both projects are pretty far from being usable right now.

Awesome suggestion. Just started using this (was on Swiftkey) and it’s awesome, especially after adding in the library for glide typing.
