Fox Bridge por DKazerBR

Fox Bridge connects Firefox to your AI assistant through the Firefox Bridge local companion and the Model Context Protocol (MCP).

Read pages, fill forms, click observed controls, capture screenshots, and manage tabs. For development work, collect console errors, inspect elements and styles, and examine network and performance metadata. Optional capabilities include bookmarks, browsing history, tab groups, and file transfers.

The extension starts paused. Enable access in its panel and choose which sites and capabilities your assistant can use. The browsing default allows HTTP/HTTPS sites once enabled; explicit site blocks take precedence. Debugging and file transfers need separate grants. You can pause access or release a controlled tab at any time.

One-time companion setup is required. Install Node.js 22 or later, extract the Firefox Bridge local package, run its setup helper, and connect your MCP client. The extension then connects automatically, with no pairing key to copy. Installing the extension alone does not install the companion or configure an AI assistant.

Requested page content, screenshots, and debug observations pass to your connected MCP client. That client may process them using a cloud service. Fox Bridge has no developer telemetry service.

Input events are synthetic, so some sites and native dialogs require manual interaction. The extension cannot control private tabs or protected browser pages, and its debug tools do not replace all Firefox DevTools features.
