QntmBlock 作者： quantumbrowser.dev

QntmBlock is a free, open-source browser extension that transforms your YouTube ad experience. Instead of blocking ads, it blurs, mutes, speeds them up, and offers advanced detection evasion—making interruptions less harsh while still supporting creators.

Core Features:
Visual Treatment: Ads are smoothly blurred/masked for a seamless transition.
Auto Mute: All ad audio is automatically muted so you can stay focused.
Speed Up: Ads play at up to 32x speed to get you back to your video faster.
Full Control: Easily toggle features and adjust features speed from the popup menu.
Mask Effect (part of visual treatment): Completely covers ads with YouTube's background color (adapts to dark/light mode| supports the ytb gradient also).
Legit Mode & Randomization: New modes to help avoid detection by YouTube, including randomized behaviors.
Dynamic Detection: Advanced ad and DOM detection methods to stay ahead of YouTube's countermeasures.

Why QntmBlock?
Lightweight & Fast: Pure JavaScript and Rusts WebAssembly, no heavy libraries, but there is still some impact on browser performance.
Creator Friendly: Ads are modified, not blocked — creators still receive ad revenue.
Stealthy & Undetected: Works client-side, does not block web requests, making it invisible to YouTube.
100% Open Source: All code is available on GitHub. Inspect, contribute, and trust what it does.
