Drive Firefox-based browsers (Floorp, LibreWolf, Zen, Waterfox, Mullvad, Firefox) from any MCP client — read pages, screenshot, click, fill forms and manage tabs in your real session, over Marionette/WebDriver. OS input & JS eval locked by default.
Enables MCP-capable CLIs to operate real, already-logged-in Firefox tabs via a WebExtension and native messaging, without simulated input. Supports navigation, clicking, typing, reading, screenshots, and console/network capture with policy gating and frame awareness.
Enables browser automation, including navigation, form filling, login with CAPTCHA handling, and element manipulation, using a Chrome-based MCP server.
