Camoufox - Stealth Firefox for Undetectable Scraping

Camoufox is a stealth-patched version of Firefox designed specifically for web scraping and automation. Unlike Chromium-based stealth solutions, it takes a different approach by modifying Firefox at the C++ level, making detection significantly harder.

What Makes Camoufox Different

Most stealth tools patch detection at the JavaScript level, which anti-bot scripts can detect. Camoufox patches Firefox's source code directly:

• No JavaScript patches, Fingerprint spoofing happens at the C++ engine level
• No CDP leaks, Firefox uses a different remote protocol than Chromium
• Realistic fingerprints, Generates device-consistent fingerprints from a BrowserForge database
• Human-like characteristics, Screen dimensions, fonts, and locale all match the spoofed OS

Installation

pip install camoufox
camoufox fetch  # Downloads the patched Firefox binary

Basic Usage

from camoufox.sync_api import Camoufox

with Camoufox() as browser:
    page = browser.new_page()
    page.goto("https://bot.sannysoft.com")
    page.screenshot(path="camoufox_test.png")
    print(page.title())

With Custom Fingerprint and Proxy

from camoufox.sync_api import Camoufox

with Camoufox(
    os="windows",  # Spoof Windows fingerprint
    proxy={
        "server": "http://proxy.example.com:8080",
        "username": "user",
        "password": "pass"
    },
    humanize=True,  # Add human-like mouse movements
    screen={"width": 1920, "height": 1080}
) as browser:
    page = browser.new_page()
    page.goto("https://protected-site.com")
    page.wait_for_load_state("networkidle")
    content = page.content()
    print(content[:500])

Async Support

import asyncio
from camoufox.async_api import AsyncCamoufox

async def scrape():
    async with AsyncCamoufox(humanize=True) as browser:
        page = await browser.new_page()
        await page.goto("https://nowsecure.nl")
        await page.wait_for_timeout(5000)
        title = await page.title()
        print(f"Title: {title}")

asyncio.run(scrape())

When to Use Camoufox

Choose Camoufox when:

• Chromium-based stealth tools are being detected
• You need a self-hosted browser automation solution
• The target site specifically fingerprints Chromium

Choose ScraperAPI instead when:

• You need to scale to thousands of concurrent requests
• You want zero infrastructure management
• You prefer a simple HTTP API over browser automation

Limitations

• Slower than HTTP-level scraping (it is still a full browser)
• Firefox has lower market share, which can be a signal on sites that track browser distribution
• Requires downloading the patched Firefox binary (~100MB)

Camoufox is one of the best self-hosted stealth browser options available and a strong alternative when Chromium-based tools fail.
