Every patch leaves a fingerprint of its own. CreepJS has an entire battery of "lies detectors" built around this. +2. **Chromium itself is now suspect.** Residential-proxy bot traffic is overwhelmingly Chromium-based, so detectors weight anything Chromium-shaped as risky by default. And the parts that matter (TLS stack, renderer process) are not fully open-source in Chrome proper - forks either inherit all Chromium tells or drift in visible ways. + +**stealthfox patches Firefox at the C++ level.** The spoofed values come back out through the normal Gecko paths - there is no JS shim, no override, no `Object.defineProperty`. **From the page's point of view, the browser is just telling the truth.** Anti-bot lie-detectors have nothing to latch onto. + +stealthfox spoofs **all the layers that matter, together, coherently**: + +| Layer | What we do | Why it matters | +|-------|-----------|-----------------| +| Navigator / hardware | C++ overrides: UA, oscpu, languages, hardwareConcurrency, deviceMemory, storage quota | Self-description coherent across every API | +| Screen / window / pointer | C++ patch: screen WxH, outerSize bound, media-query device-size, pointer/hover/touch capabilities | `screen.*`, `window.outer*`, CSS `@media (pointer: fine)` all coherent | +| CSS system colors | 40 `ui.*` Win32 palette overrides | `getComputedStyle()` on system colors matches real Windows | +| GPU / WebGL | C++ patch: vendor, renderer, extensions whitelist, integer/float params, shader precisions, readPixels noise | Matches real Windows ANGLE down to enum values | +| Canvas 2D | C++ patch: per-pixel substitution + geometry skip-mask noise + TextMetrics variance | Defeats canvas hashing and text-metrics fingerprinting | +| Fonts / DirectWrite | C++ patch: family whitelist + fabricated authoritative list + per-family width scale + DWrite settings | Font enumeration matches real Win10; canvas text hash stable | +| Audio | C++ patch: sampleRate + output latency + max channels + AnalyserNode/DynamicsCompressor noise | AudioContext fingerprints bucket users very tightly | +| Speech synthesis | C++ patch: fabricated voices list | `navigator.speechSynthesis.getVoices()` matches the spoofed OS | +| WebRTC | C++ patch (nICEr): srflx address swap + synthetic srflx fallback + private-LAN host candidates | Real public IP never leaks via STUN | +| Timezone | C++ patch: per-Realm TZ via BrowsingContext (no IPC pref races) | `Date.getTimezoneOffset()`, `Intl.DateTimeFormat` match the spoofed location | +| DevTools detection | C++ patch: `Debugger.stealthMode` + Juggler `Runtime.js` + thread actor | FP Pro `developer_tools` = Not detected even with debugger attached | +| SOCKS5 auth | C++ patch | Stock Playwright+Firefox cannot negotiate it at all | +| DNS | Routed through SOCKS proxy by default | No DNS leak when using a residential gateway | +| Mouse motion | Bezier curves inside Juggler `PageHandler.js`, ~10 ms per waypoint | Even `page.click(selector)` moves like a human | +| GPU on virtual desktop | Pref-driven workaround for FF150 alt-desktop sandbox regression | WebGL renderer populated even in headless / multi-worker mass tests | +| Fission navigation | C++ patch: `nsDocShell` + `CanonicalBrowsingContext` Juggler navigation fix | `page.goto()` reliable on FF150 across proxy edge cases | +| about:newtab race | Async wrapper sleep around `new_page()` | No "Navigation interrupted by about:newtab" on FF150 | +| Proxy reliability | Juggler `PageHandler.equalsExceptRef` split try/catch | No spurious "Invalid url" with proxies like Evomi | + +Everything is driven by preferences - no hardcoded values in the binary.

For example `gpu_class_tier` conditions `screen.tier`, `hardware.concurrency` and `webgl.msaa_samples`. A high-end GPU will tend to pair with a 2560x1440+ screen and 16+ cores. + +When you pin a field: + +1. The pinned value is written directly, bypassing the sampler. +2. **Unpinned children are still sampled from their conditionals** — using the parent's original posterior, not the pinned value. + +That last point is the subtle one: pinning breaks the conditional chain. If you pin `gpu.renderer` to an RTX 4090 string but leave `screen` unpinned, the sampler will pick `screen` from the seed-derived tier (which might be `low_end`), producing a physically implausible "RTX 4090 + 1366x768" pairing. + +**Rule of thumb:** pin correlated fields together, or just trust the sampler. + +## Full list of pinnable keys + +Keys are dotted paths. All values are optional — omitted keys fall back to the sampler. + +### `gpu.*` + +| Key | Type | Example | Notes | +|-----|------|---------|-------| +| `gpu.class_tier` | str | `"high_end"` | The **root** of the Bayesian network. One of `"low_end"`, `"mid_range"`, `"high_end"`, `"integrated_old"`, `"integrated_modern"`. Pin this alone to steer the whole profile (screen, concurrency, MSAA, …) toward a coherent tier without having to name each sub-field. | +| `gpu.vendor` | str | `"Google Inc. (NVIDIA)"` | Must exactly match the renderer vendor prefix, otherwise detectors catch the mismatch. | +| `gpu.renderer` | str | `"ANGLE (NVIDIA, NVIDIA GeForce RTX 4090 Direct3D11)"` | Windows ANGLE string. Used by WebGL `UNMASKED_RENDERER_WEBGL`. | + +**Why `class_tier` is pinnable separately from `renderer`.** They live at different levels of abstraction: + +- `class_tier` is a **coarse handle** over the whole Bayesian graph. It gates the distribution of `screen`, `hardware.concurrency`, `webgl.msaa_samples`, and storage quota. Pin `{"gpu.class_tier": "low_end"}` and the sampler returns a *coherent* low-end machine — small screen, 2-4 cores, 4x MSAA — without you having to specify each field. +- `renderer` is an **exact string** that lands verbatim in WebGL's `UNMASKED_RENDERER_WEBGL`. Useful when you want to imitate a specific GPU the target site has seen before. Does **not** condition other fields — if you pin `renderer` to an RTX 4090 but leave `class_tier` unpinned, `class_tier` is re-sampled from scratch and might disagree with the renderer string (see [How sampling + pinning interact](#how-sampling--pinning-interact)). + +In practice most users should pin `class_tier` alone, or pin `renderer`+`vendor`+`class_tier` together if they want full control. + +### `screen.*` + +| Key | Type | Example | +|-----|------|---------| +| `screen.width` | int | `2560` | +| `screen.height` | int | `1440` | +| `screen.avail_width` | int | `2560` | +| `screen.avail_height` | int | `1400` | +| `screen.dpr` | float | `1.0`, `1.25`, `1.5`, `2.0` | +| `screen.tier` | str | `"1080p"`, `"1440p"`, `"4k"`, ... | + +### `hardware.*` + +| Key | Type | Example | Notes | +|-----|------|---------|-------| +| `hardware.concurrency` | int | `16` | `navigator.hardwareConcurrency`. | +| `hardware.storage_quota_mb` | int | `10_000` | `navigator.storage.estimate().quota / 1024²`. | + +### `audio.*` + +| Key | Type | Example | Notes | +|-----|------|---------|-------| +| `audio.sample_rate` | int | `48000`, `44100` | `AudioContext.sampleRate`. | +| `audio.output_latency_ms` | float | `20.0` | `AudioContext.outputLatency * 1000`. | +| `audio.max_channel_count` | int | `2`, `6`, `8` | `AudioDestinationNode.maxChannelCount`. | + +### `codec.*` (booleans) + +| Key | Effect | +|-----|--------| +| `codec.av1_enabled` | `true` → `canPlayType('video/av01')` returns `"probably"`. | +| `codec.webm_encoder_enabled` | `MediaRecorder` advertises WebM support. | +| `codec.mediasource_webm` | `MediaSource.isTypeSupported('video/webm')`. | +| `codec.mediasource_mp4` | `MediaSource.isTypeSupported('video/mp4')`. | +| `codec.webspeech_synth` | `speechSynthesis.getVoices()` returns a fabricated voice list. | + +### `webgl.*` + +| Key | Type | Example | Notes | +|-----|------|---------|-------| +| `webgl.msaa_samples` | int | `4`, `8`, `16` | `MAX_SAMPLES` WebGL parameter.
