Initial release of Tetherweb — a developer tool that connects Firefox to Claude Code via the Model Context Protocol (MCP).

What it does:
• 30+ MCP tools: DOM interaction, screenshots, network capture, cookie access, tab management
• Native OS-level click support via cliclick
• On-demand HTTP traffic capture including request/response bodies
• HttpOnly cookie read/write for auth debugging
• WebSocket message capture
• Explicit consent gate — all commands blocked until user completes onboarding

No cloud or third-party servers. The extension only communicates with a locally-running process over localhost.
