Boring YouTube is a lightweight browser extension that turns all YouTube thumbnails greyscale, inspired by Arc browser's beloved Boring YouTube Boost by Simon Beel.
Think about it: those bright, eye-catching thumbnails are designed to grab your attention and keep you scrolling. By removing the visual noise, you can focus on the content that actually matters to you — not what the algorithm thinks will get the most clicks.
It's that simple. Greyscale thumbnails = less distraction = more intentional viewing.
✅ Instant Greyscale - Converts all YouTube thumbnails to greyscale automatically
✅ Smart Fullscreen Detection - Automatically disables when you're watching videos fullscreen
✅ Dynamic Content Ready - Works seamlessly with YouTube's single-page application
✅ Cross-Platform - Available for Firefox, Chrome and Edge
✅ Lightweight & Fast - Minimal performance impact, maximum focus
✅ Toggle Control - Easy on/off switch
✅ Developer Friendly - Clean, shared codebase architecture
✅ Zero Tracking - No data collection, no analytics, just pure functionality
