• Critical fix: response body capture is now disabled by default. The previous version attached a stream filter to every XHR request continuously, causing significant Firefox slowdowns on sites like Google Chat, Gmail, and other ServiceWorker-heavy pages.
• Response body capture can now be enabled on demand via the set_response_body_capture MCP tool when needed, and disabled when done.
• Fixed memory leak: response body chunks are now properly cleaned up when requests fail.

• Configurable bind address: by default the MCP server now binds to 127.0.0.1 (loopback only). Set TETHERNET_HOST=0.0.0.0 in the MCP server config to expose it on all interfaces — useful when Firefox and Claude run on different machines.

• Co-pilot mode improvements: the agent now detects JavaScript framework pages (React, Vue, Angular, Next.js) upfront and switches to guided screenshot mode immediately, rather than attempting DOM automation that won't work on SPAs.

• Co-pilot reliability: the agent now takes its own screenshots to navigate instead of asking you to describe what you see on screen.
