About this extension

⚡ PureYouTube

Ultra-lightweight cinematic immersion and bloat-free performance.

🎬 Cinematic Experience

Full-Viewport Cinema: Automatically scales the player to 100% screen height, pushing the header and details out of sight for total immersion.
Layout Stabilization: Enforces a pitch-black background immediately to prevent "white flashes" and UI shifting during loading.

🚀 Pure Performance

Telemetry Neutralizer: Disables YouTube's internal tracking (ytcsi, ytStats) by replacing them with empty functions, saving CPU cycles.
Ultra-Lightweight: Zero dependencies. No heavy background scripts or complex request interceptions—just raw, optimized CSS and JS.

🧹 Clutter-Free UI

Aggressive Declutter: Instantly hides ads, live chats, merch shelves, and distracting "glow" effects.
Smart Lifecycle: Uses a MutationObserver to ensure the layout stays perfect during internal navigation without draining your battery.
