invisible-firefox 0.2.1

Antidetect browser profile manager for the patched Firefox (manual use).

Run many undetectable browser profiles on one patched Firefox.

One desktop app, many identities. Each profile is a distinct fingerprint (GPU, canvas, fonts, audio, WebRTC) set at the C++ source level plus its own proxy and saved logins, so every profile passes bot detection on its own. Hit Launch and a real Firefox window opens with that identity.

Install

pip install invisible-firefox
python -m invisible_firefox

Everything it needs is downloaded automatically, nothing to fetch by hand: the patched Firefox binary (once, SHA256-verified, cached) the moment the app opens, and the GeoIP database when a proxy needs it. Runs on Windows, Linux and macOS.

Built on invisible_core; it launches the binary directly, no Playwright.

What you get

• One identity per profile - GPU, screen, fonts and ~400 other fields from a seed, stable across launches.
• Persistent - each profile keeps its own cookies, storage and logins in its own directory.
• Per-profile proxy - none, or sx.org residential, with country and city per profile.
• Live status - see which profiles are running; close the browser and the list updates itself.

Proxies

Around 90% of proxies are public, so their IPs are already known and blocked. For the clean 10%, residential IPs that aren't already known, we recommend sx.org: set your API key once in the Proxies menu, then pick a country and city per profile. New accounts get 3 GB free with code STEALTH.
