Firefox Control

High risk

This MCP server provides AI assistants with access to the browser's tab management, browsing history, page search, and webpage text content through a local MCP (Model Context Protocol) connection. Before accessing any webpage content, explicit user consent is required for each domain through browser-side permissions. Note: This extension requires a separate Firefox add-on component, which is available at [https://addons.mozilla.org/en-US/firefox/addon/browser-control...

Security assessment

Plutonium assessed this web connector for permissions, capabilities, and security-relevant behavior.

  • Reads your private information: This connector can read data the connected service holds about you - documents, messages, contact lists, source code, customer records, or saved profile details - and pass it back to the AI.
  • Can permanently delete data: This connector can erase records, files, or accounts. Once deleted the data may be unrecoverable - even an accidental request can cause permanent loss.
