Features & Capabilities

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

Is Boring YouTube Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Boring YouTube requires a few sensitive permissions. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Boring YouTube is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
