LibreWolf

Independent Firefox fork with telemetry stripped, uBlock Origin preinstalled, and privacy-by-default.

LibreWolf is a community-driven Firefox fork that removes all telemetry, studies, and sponsored-content hooks Mozilla bakes in. It ships with uBlock Origin preinstalled, disables WebGL and DRM by default to reduce fingerprinting surface, and enforces strict tracking protection. Unlike hardened Firefox configs you maintain yourself, LibreWolf bakes those choices into the build — fewer footguns, faster setup. It tracks Firefox ESR releases closely but adds its own release signing and update infrastructure for independence.

Best for

Desktop users wanting Firefox's engine without Mozilla telemetry or manual about:config hardening.
