Show HN: T3rnel Browser – drive the browser you're signed into (t3ratech.github.io)

T3rnel Browser is a browser extension + MCP bridge that gives an AI agent the browser you are already signed into, instead of launching a fresh automated browser and asking it to re-authenticate. The side panel lets a human see what the agent is doing and refuse actions. It now supports 24 languages, light/dark modes, React inspection, cache/hard reload, an infinite-scroll stop guard, and dark-mode PDF export.
