+          C++ source patches against mozilla-central that harden Firefox against
+          browser fingerprinting at the source level (Canvas, WebGL, AudioContext,
+          Fonts, WebRTC, Timezone, DevTools detection). MPL-2.0. Distributed as
+          patches you apply with `git am`, or as a pre-built binary on the release
+          page. Different angle from LibreWolf, which ships a configured Firefox
+          fork - firefox-stealth changes the engine itself.
