Firefox DevTools Integration Skill

Purpose

This skill enables seamless integration of Firefox Remote Debugging Protocol (RDP) for development workflows through mcporter. It configures Firefox to accept remote debugging connections and provides tooling for Agent-driven browser interaction and debugging.

Prerequisites [CRITICAL]

mise x node@20 -- mcporter call 'firefox-devtools.getVersion'

Should return Firefox version info (JSON). If it fails, Firefox isn't listening on port 6000.

Core Concepts

Firefox Remote Debugging Protocol (RDP)

Firefox uses RDP over WebSocket connections on port 6000 by default, exposed through mcporter for Agent interaction.
