Camofox Default Browser

Use Camoufox browser (Firefox fork with advanced fingerprint management) as OpenClaw's browser automation engine. The camofox_* tools handle anti-bot protection that standard Chromium/Playwright automation may trigger, enabling reliable automation for authorized tasks.

When to Use

Use camofox_* when the built-in browser tool encounters blocking — for external public websites with anti-bot protection
The built-in browser tool (Playwright/Chromium) may be detected by Google, LinkedIn, Amazon, Cloudflare, and most WAFs. Camoufox manages fingerprints at the C++ implementation level, reducing detection risk.

Reason

Camoufox manages browser fingerprints at the C++ implementation level: navigator.hardwareConcurrency, WebGL renderer, AudioContext, screen geometry, WebRTC — all handled before JavaScript evaluation. This provides more reliable automation compared to standard stealth plugins that can themselves be fingerprinted.

Available Tools

Tool	Purpose
camofox_create_tab	Open a new anti-detection browser tab with isolated context
camofox_snapshot	Accessibility tree snapshot (~90% smaller than raw HTML) with stable element refs (e1, e2, e3) plus optional base64 screenshot
camofox_click	Click element by ref (e.g. "e3") or CSS selector
camofox_type	Type text into form field. Set pressEnter=true to submit
camofox_navigate	Navigate to URL or use search macro: @google_search, @youtube_search, @amazon_search, @reddit_search, @linkedin_search, @wikipedia_search, @twitter_search, @yelp_search, @spotify_search, @instagram_search, @tiktok_search, @twitch_search, @netflix_search
camofox_scroll	Scroll page up/down by pixel amount
camofox_screenshot	Capture screenshot of current page
camofox_close_tab	Close tab to free resources
camofox_evaluate	Execute JavaScript in page context
camofox_list_tabs	List all open tabs
camofox_import_cookies	Import Netscape cookie file for authenticated browsing (requires CAMOFOX_API_KEY)

Workflow

camofox_create_tab(url="https://example.com") → tabId
camofox_snapshot(tabId="") → accessibility tree
camofox_click/type(tabId="", ref="e3") → interact
camofox_close_tab(tabId="") → cleanup

Resource Management

Server auto-starts with OpenClaw Gateway (default port 9377)
Browser engine launches lazily on first tab request
Idle browser shuts down after configurable timeout (default 5 min)
~40MB memory when idle, ~200MB with active browser session
Session isolation: separate cookies/storage per user
Health endpoint: GET http://localhost:9377/health
Crash telemetry: anonymized (no page content, cookies, IPs). Opt out via CAMOFOX_CRASH_REPORT_ENABLED=false

⚠️ Security & Usage Guidelines

Cookie Import: Session cookies are bearer tokens that grant full account access. Treat imported cookie files as live credentials. Only import cookies you own or have explicit authorization to use.
Authorized Use Only: This tool is designed for legitimate automation tasks where you have permission to access the target service. Do not use to circumvent access controls on sites where you lack authorization.
Legal Compliance: Ensure your automation complies with target site Terms of Service, applicable laws, and regulations. Unauthorized scraping or access may violate computer fraud laws.
Privacy: Do not automate access to accounts or data you do not own or have explicit permission to access.
Risk Awareness: Imported session cookies may bypass normal login safeguards. Mishandling can lead to unauthorized account actions or session hijacking.

Dependencies & System Requirements

System Dependencies (Linux / Debian-based)

The following packages are required for Camoufox to render pages correctly, handle UI elements, and operate in both headful and headless environments.

Package	Purpose
`libgtk-3-0`	GTK+ 3 toolkit — handles window management, widgets, and UI rendering. Required for all GUI operations including snapshot screenshot capture.
`libgdk-pixbuf2.0-0`	Image loading library — supports PNG, JPEG, WebP, and SVG rendering for page images, favicons, and CSS background assets.
`libdbus-glib-1-2`	D-Bus GLib bindings — enables IPC communication between browser processes, desktop integration, and system service discovery (e.g., notification daemon).
`libxt6`	X11 Toolkit library — legacy X11 client support needed by certain embedded XPCOM components and older extensions.
`libxcomposite1`	X Composite Extension — compositing manager support required for GPU-accelerated layer composition and correct rendering of overlaid elements.
`libxdamage1`	X Damage Tracking Extension — notifies compositor of painted regions for incremental redraws; critical for correct snapshot captures on accelerated surfaces.
`libxfixes3`	X11 Extension Fixes — provides cursor shape, region, and atom operations needed by WebGL canvas and pointer events.
`libxrandr2`	X Resize and Rotate — monitors display mode changes (DPI scaling, rotation, multi-monitor hotplug); required for responsive layout rendering.
`libatk-bridge2.0-0`	ATK Accessibility Bridge — translates accessibility tree data from Firefox's internal AT-SPI layer into format consumed by Playwright snapshots. Without this, accessibility tree output is incomplete or empty.
`libdrm2`	Direct Rendering Manager — DRM/KMS interface used by hardware video decode pipelines and OpenGL ES context creation on supported GPUs.
`libgbm1`	Graphics Buffer Manager — abstraction layer over DRM/GLES for buffer allocation; required for offscreen rendering, headless snapshots, and WebGPU compute fallbacks.
`xvfb`	X Virtual Framebuffer — provides a headless X11 server so Camoufox can run without physical display hardware. Essential for CI/CD, cron jobs, and containerized deployments. Start with `Xvfb :99 -screen 0 1920x1080x24` and set `DISPLAY=:99`.

All libraries above are available via standard Debian/Ubuntu package repositories (apt). For Alpine Linux, equivalents exist but must be cross-compiled alongside Camoufox since pre-built binaries target glibc distributions.

Node.js Requirements

Requirement	Minimum	Recommended
Version	Node.js 16 LTS	Node.js 20 LTS
npm	8.x+	10.x+
Architecture	x64 (amd64), arm64	Same as Camoufox binary
Memory overhead	~15 MB per worker process	—

Camoufox is distributed as a native C++ server — there are no npm dependencies. The only JavaScript requirement is Node.js itself to bootstrap the OpenClaw tool integrations. Both global (npm i -g) and local installation paths work identically since the server communicates via HTTP localhost API.

Browser Engine

Aspect	Specification
Base engine	Mozilla Firefox fork (ESR-aligned)
Binary path	Default: `/root/.cache/camoufox/camoufox`
Supported architectures	`linux-x64` (primary), `linux-arm64` (secondary)
Download URL	https://github.com/jo-inc/camofox/releases
Idle memory footprint	~40 MB (browser process, no tabs)
Active memory footprint	~200 MB (one tab loaded, JS evaluated)
Multi-tab scaling	+~50 MB per additional tab
Crash telemetry	Enabled by default (anonymized, no cookies/IPs). Disable via env var.

The Camoufox binary is downloaded and cached automatically by the camofox_* tool runtime on first use. To force re-download, delete the cache directory before next session start.

Environment Variables

Variable	Required	Default	Description
`CAMOUFOX_EXECUTABLE`	Yes	—	Absolute path to the Camoufox binary. Must point to an executable file. Without this, the server cannot launch the browser engine.
`CAMOFOX_API_KEY`	No	—	API key for authenticated cookie import operations (`camofox_import_cookies`). Required when importing session cookies from Netscape-format files.
`CAMOFOX_CRASH_REPORT_ENABLED`	No	`true`	Toggle anonymized crash telemetry. Set to `false` to disable crash reports sent to the upstream collector.
`PORT`	No	`9377`	TCP port on which the Camoufox HTTP API server listens. The server binds to `0.0.0.0` by default.
`DISPLAY`	Conditional	`:0`	X11 display variable. Only required when running outside WSL/container where auto-detection fails. Set explicitly if headless mode doesn't activate.
`XDG_RUNTIME_DIR`	Conditional	—	XDG runtime directory for D-Bus socket discovery. Required in containerized environments (e.g., Docker, Kubernetes pods) where systemd isn't present.

Optional Dependencies

These packages are not strictly required for basic browsing automation but improve compatibility:

Font packages (fonts-liberation, fonts-noto-color-emoji, fonts-wqy-microhei): Provide proper CJK, emoji, and Western text rendering. Without fonts, PDF exports may show blank boxes and some websites fall back to generic monospace.
Shared MIME info (shared-mime-info): Enables correct MIME-type detection for downloaded files (PDFs, images, archives).
Alsa / PulseAudio (libasound2, libpulse0): Audio playback support needed for sites with embedded video/audio that attempt to initialize audio contexts.
Video codecs (libavcodec-extra, libavformat-extra): H.264/AAC decoding for HTML5 video players. Firefox ships with open formats (VP8/VP9, Ogg Vorbis) by default; proprietary codecs require additional packages.
Cups (cups-client, libcupsys2): Print-to-PDF functionality. Required if automation involves printing web pages.
