Add firefox-stealth (Firefox hardening patches) to Browsers

[feder-cr]

C++ source patches against mozilla-central that harden Firefox against browser fingerprinting at the source level (Canvas, WebGL, AudioContext, Fonts, WebRTC, Timezone, DevTools detection - 15 patches). MPL-2.0.

Different angle from LibreWolf, which ships a configured Firefox fork: firefox-stealth changes the engine itself, distributed as .patch files you apply with git am, or as a pre-built binary on the release page.

No telemetry, no tracking on the project page. Self-disclosure: I am the author.

An issue I see with this, is you're pinning it to a specific sha. So there's no update path. You won't get any security patches without a manual rebase on every release.
But seems your goal here is for anti-bot detection rather than privacy(?), if so not going to be suitable for here.

Closing anyway, as the other standards aren't met (see requirements), and your PR is invalid (see bot comment).

For privacy, something like LibreWolf is going to win: well-maintained, good distribution, solid privacy. Or, even just Firefox plus a good user.js.
