Claudezilla brings Firefox browser automation to Claude Code CLI — Anthropic's AI coding
assistant for the terminal.

Control Firefox directly from your terminal: navigate pages, click elements, fill forms,
capture screenshots, and analyze page content. A Google-free alternative to Chrome-based
browser automation.

FEATURES:
- Page navigation and full DOM interaction (click, type, scroll, press keys)
- Screenshot capture with dynamic readiness detection and image compression
- Annotated screenshots with numbered element badges for precise interaction
- Structured page analysis via JSON (faster and cheaper than screenshots)
- Accessibility tree snapshots for semantic page understanding
- Page state diffing to detect changes between interactions
- Domain allowlists for agent sandboxing
- Flexible element waiting (CSS selector, text content, or URL pattern)
- Network request and console log monitoring
- Multi-agent safety with tab ownership, screenshot mutex, and slot reservations
- Expression validation that blocks dangerous JS patterns (eval, fetch, cookies)
- Focus loops for persistent iterative development across sessions
- Orphaned tab cleanup for crashed or disconnected agents
- Per-operation timeouts (5s–300s, default 150s)

REQUIREMENTS:
- Claude Code CLI installed
- Native messaging host (one-command install script)
- Firefox 91+
- macOS, Linux, or Windows 10/11

PRIVACY:
- All communication is local via Unix socket (no network exposure)
- No data collected or transmitted to external servers
- Page content accessed only on explicit tool invocation
- Console and network capture are opt-in
- Request bodies are never captured
- Open source (MIT license)
