LibreWolf

Firefox privacy taken to the limit

Overview

LibreWolf is a community fork of Mozilla Firefox that removes telemetry, data collection, and sponsors, applying privacy-maximizing defaults while keeping Firefox features and extension compatibility.

uBlock Origin is bundled, so no separate ad blocker is needed. RFP (Resist Fingerprinting), strict cookie/referrer controls, and removal of built-in Google/Bing search engines are all applied by default.

Desktop only (Windows/macOS/Linux)—no mobile build. Best for advanced users who want maximum privacy without manual hardening or any telemetry at all.
