YouTube In-Video Popup Blocker od WhatHack

YouTube In-Video Popup Blocker is a lightweight extension that automatically removes distracting overlays from YouTube videos. It blocks:

In-video cards (the pop-ups that appear during playback)
Classic annotations (legacy pop-up notes and links)
YouTube promotional overlays (such as “Try YouTube Premium” banners and paid content disclosures)

Enjoy a cleaner, distraction-free YouTube viewing experience while preserving essential features like end cards and the subscribe button.

No configuration is required—just install and enjoy uninterrupted videos.

This extension is currently in beta.
