In short

LibreWolf is free and open source; its project repository is licensed under MPL-2.0^8,9.
It ships with uBlock Origin included and Tracking Protection set to strict mode^1,2.
Desktop builds exist for Windows, macOS and Linux; the FAQ says nobody is working on an Android version^3,6.
It turns off the built-in password manager and Google Safe Browsing by default^2,3.

LibreWolf suits people who want Firefox with strong privacy settings already applied, including uBlock Origin and fingerprinting resistance^1,2. It costs nothing and its patches are public⁸. The catch: it has no mobile app, no built-in password manager, no Safe Browsing warnings by default and no built-in auto-update^2,3.

Best for: People who want a hardened Firefox with ad and tracker blocking from the first launch.
