 **invisible_playwright patches Firefox at the C++ level.** The spoofed values come back through normal Gecko paths - no JS shim, no override, no `Object.defineProperty`. From the page's point of view, the browser is just telling the truth. It spoofs all the layers that matter: Navigator, screen, GPU/WebGL, Canvas, fonts, audio, WebRTC, timezone, DevTools, SOCKS5. See [feder-cr/invisible_firefox](https://github.com/feder-cr/invisible_firefox) for the full per-layer breakdown.
 
+**The one thing the browser can't fix: the IP you come from.** A C++-perfect fingerprint still looks wrong behind a burned proxy, and around 99% of proxies out there are public and widely shared, so the strictest anti-bot setups flag those IPs on sight. The browser side is solved here; for the other 1%, clean residential IPs that aren't already burned, we partner with [sx.org](https://sx.org/?c=invisible_playwright).
