Best Firefox MCP Servers
Firefox is a web browser created by Mozilla that emphasizes privacy, security, and customization while providing a fast browsing experience with strong privacy protections.
Why this server?
Partially supports browser automation in Firefox through the T3rnel Browser extension, with limitations due to Firefox lacking a debugger API.
AlicenseAqualityAmaintenanceDrives the browser you are already signed into, so work behind a login, SSO or MFA needs no scripted auth. A local stdio MCP server talking to the free T3rnel Browser extension over a native-messaging relay. 20 tools standalone; 99 with the extension — CSS-as-component export, full-page capture, React inspector, network and console capture, form filling, record and replay. Nothing hosted.22253 npm2Apache 2.0Why this server?
Supports configuration of Firefox browser profiles through the browser kernel configuration
