Verified · today

Control and debug Firefox: navigate, fill forms, inspect network and console, profile.

Install

claude mcp add firefox-devtools-mcp -- npx -y @mozilla/[email protected]

Requires: FIREFOX_HEADLESS, START_URL

Our take

Firefox DevTools MCP lets agents drive and inspect Firefox sessions, including navigation, form interaction, console output, network traffic, and profiling. It is most useful for developers and QA workflows that need browser automation with Firefox-specific debugging depth. Strong star count and Mozilla namespace are positive maturity signals, though it remains a developer-tooling integration rather than a general web automation server.
