About YouTube Live Chat Fullscreen

YouTube's fullscreen mode hides the chat. This extension brings it back — as a transparent, draggable overlay right on your video. Features: 💬 Chat in fullscreen — Post comments and Super Chats directly from the overlay. 🖱️ Drag, resize, reposition — Put the chat window exactly where you want it. 🎨 Style it your way — Background, text color, font size, blur, spacing. 📋 Save presets — One-click switch between styles for different streams. 🌗 Light and dark themes — Follows your system, or set it manually. 📼 Archive support — Works with chat replay on archived streams too. 🌐 50+ languages supported. No account required. No data collected. Fully open source. How to use: 1. Install the extension. 2. Open a YouTube live stream or archive with chat replay. 3. Go fullscreen — flip the switch at the bottom-right. 4. Drag, resize, and make it yours. Questions, ideas, or bug reports? We'd love to hear from you on GitHub.
