## Description

Browser MCP Bridge connects your Firefox to a locally-running Model Context Protocol (MCP) server, letting an MCP-compatible client automate the browser you already have open.

What it can do:
• Tabs — list every tab (stable id, title, url) across all windows; open, switch, and close tabs.
• Read pages — accessibility snapshots, CSS-selector queries, text/HTML/attributes, page screenshots, and console logs.
• Network — capture per-tab HTTP requests including method, URL, status, content-type, and request/response bodies (great for inspecting JSON APIs).
• Interact — click, type, hover, select options, press keys, scroll, and navigate.

How it works: the extension is only a bridge. It connects as a WebSocket client to a server you run yourself on localhost (default ws://127.0.0.1:9010). No data is sent to any third-party or to the developer. If the local server isn't running, the extension does nothing.

Requires the companion server (open source):
• PyPI: firefox-browser-mcp — run with uvx firefox-browser-mcp
• Source &amp; docs: <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/af7e35d746afa407ac67d0885dbb531f72e80fc97ccc040eeb396ef2f8dbf1bb/https%3A//github.com/ICWR-TEAM/Firefox-Browser-MCP" rel="nofollow">https://github.com/ICWR-TEAM/Firefox-Browser-MCP</a>

Open the toolbar popup to see connection status and configure the bridge URL.
