Below is a list of patches and features implemented in Camoufox.

---

### Fingerprint spoofing

- Navigator properties spoofing (device, browser, locale, etc.)
- Support for emulating screen size, resolution, etc.
- Spoof WebGL parameters, supported extensions, context attributes, and shader precision formats.
- Spoof inner and outer window viewport sizes
- Spoof AudioContext sample rate, output latency, and max channel count
- Spoof device voices & playback rates
- Spoof the amount of microphones, webcams, and speakers available.
- Network headers (Accept-Languages and User-Agent) are spoofed to match the navigator properties
- WebRTC IP spoofing at the protocol level
- Geolocation, timezone, and locale spoofing
- Battery API spoofing
- etc.

### Stealth patches

- Avoids main world execution leaks. All page agent javascript is sandboxed
- Avoids frame execution context leaks
- Fixes `navigator.webdriver` detection
- Fixes Firefox headless detection via pointer type ([#26](https://github.com/daijro/camoufox/issues/26))
- Removed potentially leaking anti-zoom/meta viewport handling patches
- Uses non-default screen & window sizes
- Re-enable fission content isolations
- Re-enable PDF.js
- Other leaking config properties changed
- Human-like cursor movement

### Anti font fingerprinting

- Automatically uses the correct system fonts for your User Agent
- Bundled with Windows, Mac, and Linux system fonts
- Prevents font metrics fingerprinting by randomly offsetting letter spacing

### Playwright support

- Custom implementation of Playwright for the latest Firefox
- Various config patches to evade bot detection

### Debloat/Optimizations

- Stripped out/disabled _many, many_ Mozilla services. Runs faster than the original Mozilla Firefox, and uses less memory (200mb)
- Patches from LibreWolf & Ghostery to help remove telemetry & bloat
- Debloat config from PeskyFox, LibreWolf, and others
- Speed & network optimizations from FastFox
- Removed all CSS animations
- Minimalistic theming
- etc.

### Addons

- Load Firefox addons without a debug server by passing a list of paths to the `addons` property
- Added uBlock Origin with custom privacy filters
- Addons are not allowed to open tabs
- Addons are automatically enabled in Private Browsing mode
- Addons are automatically pinned to the toolbar
- Fixes DNS leaks with uBO prefetching

### Python Interface

- Automatically generates & injects unique device characteristics into Camoufox based on their real-world distribution
- WebGL fingerprint injection & rotation
- Uses the correct system fonts and subpixel antialiasing & hinting based on your target OS
- Avoid proxy detection by calculating your target geolocation, timezone, & locale from your proxy's target region
- Calculate and spoof the browser's language based on the distribution of language speakers in the proxy's target region
- Remote server hosting to use Camoufox with other languages that support Playwright
- Built-in virtual display buffer to run Camoufox headfully on a headless server
- Toggle image loading, WebRTC, and WebGL
- etc.
