description: Anti-detection browser automation using Camoufox (Firefox fork with C++ fingerprint spoofing). Use when standard browser tools get blocked by Cloudflare, Akamai, or bot detection. Triggers include "stealth browse", "anti-detection", "bypass bot", "camofox", "blocked by Cloudflare", scraping protected sites (X/Twitter, Amazon, Product Hunt), or when agent-browser/playwright fails with bot detection errors.

# Camofox Browser - Anti-Detection Browser Automation

Stealth browser automation via Camoufox (Firefox fork). C++ level fingerprint spoofing — undetectable by JavaScript-based bot checks. REST API wrapper using `curl`.

## Installation

First use automatically downloads and installs the Camoufox browser (~300MB, one-time). No manual setup required — just run any `camofox` command.

## Quick Start

```bash
camofox open https://example.com          # Open URL (auto-starts server)
camofox snapshot                          # Get page elements with @refs
camofox click @e1                         # Click element
camofox type @e2 "hello"                  # Type text
camofox screenshot                        # Take screenshot
camofox close                             # Close tab
```

## Core Workflow

1. **Navigate**: `camofox open <url>` — opens tab and navigates
2. **Snapshot**: `camofox snapshot` — returns accessibility tree with `@e1`, `@e2` refs
3. **Interact**: Use refs to click, type, select
4. **Re-snapshot**: After navigation or DOM changes, get fresh refs
5. **Repeat**: Server stays running between commands

```bash
camofox open https://example.com/login
camofox snapshot
# @e1 [input] Email  @e2 [input] Password  @e3 [button] Sign In

camofox type @e1 "user@example.com"
camofox type @e2 "password123"
camofox click @e3
camofox snapshot  # Re-snapshot after navigation
```

## Commands

### Navigation
```bash
camofox open <url>                   # Create tab + navigate (aliases: goto)
camofox navigate <url>               # Navigate current tab
camofox back                         # Go back
camofox forward                      # Go forward
camofox refresh                      # Reload page
camofox scroll down                  # Scroll down (also: up, left, right)
```

### Page State
```bash
camofox snapshot                     # Accessibility snapshot with @refs
camofox screenshot                   # Screenshot to /tmp/camofox-screenshots/
camofox screenshot output.png        # Screenshot to specific path
camofox tabs                         # List all open tabs
```

### Interaction (use @refs from snapshot)
```bash
camofox click @e1                    # Click element
camofox type @e1 "text"              # Type into element
```

### Search Macros
```bash
camofox search google "query"        # Google search
camofox search youtube "query"       # YouTube search
camofox search amazon "query"        # Amazon search
camofox search reddit "query"        # Reddit search
```

13 macros available — see [references/macros-and-search.md](references/macros-and-search.md).

### Session Management
```bash
camofox --session work open <url>    # Isolated session
camofox --session work snapshot      # Use specific session
camofox close                        # Close current tab
camofox close-all                    # Close all tabs in session
```

### Server Control
```bash
camofox start                        # Start server (usually auto)
camofox stop                         # Stop server
camofox health                       # Health check
```

## Ref Lifecycle (Important)

Refs (`@e1`, `@e2`) are invalidated when the page changes. Always re-snapshot after:
- Clicking links/buttons that navigate
- Form submissions
- Dynamic content loading

```bash
camofox click @e3                    # Navigates to new page
camofox snapshot                     # MUST re-snapshot
camofox click @e1                    # Use new refs
```

## When to Use camofox-browser vs agent-browser

| Scenario | Tool |
|----------|------|
| Normal websites, no bot detection | agent-browser (faster) |
| Cloudflare / Akamai protected | **camofox-browser** |
| Sites that block Chromium automation | **camofox-browser** |
| Need anti-fingerprinting | **camofox-browser** |
| Need iOS/mobile simulation | agent-browser |
| Need video recording | agent-browser |

## Anti-Detection Capabilities

- C++ level fingerprint spoofing (canvas, WebGL, AudioContext, fonts)
- Firefox-based (not Chromium — different detection surface)
- Human-like interaction timing (`humanize` parameter)
- WebRTC leak prevention
- No `navigator.webdriver` flag

See [references/anti-detection.md](references/anti-detection.md) for details.

## Environment Variables

| Variable | Default | Description |
|----------|---------|-------------|
| `CAMOFOX_PORT` | `9377` | Server port |
| `CAMOFOX_SESSION` | `default` | Default session name |
| `CAMOFOX_HEADLESS` | `true` | Headless mode |
| `HTTPS_PROXY` | — | Proxy server |

## Troubleshooting

**Server won't start?**
```bash
camofox health                        # Check if running
camofox stop && camofox start         # Restart
```

**Still getting blocked?**
```bash
# Enable proxy
HTTPS_PROXY=socks5://127.0.0.1:1080 camofox open <url>
```

**Bot detection test:**
```bash
camofox open https://bot.sannysoft.com/
camofox screenshot bot-test.png
```

## Cleanup

Always close when done:
```bash
camofox close-all
camofox stop
```
