Restores scrollable fullscreen mode to show title, comments, likes, and related videos. Disables new UI's bottom recommendations.
UPDATE NOVEMBER 2025.
YouTube has introduced a new fullscreen UI that shows recommended videos at the bottom when you scroll. This script removes that bottom video grid while preserving the ability to scroll through comments, video information, and the traditional related videos sidebar in fullscreen mode.
Technical Implementation:
.ytp-fullscreen-grid and .ytp-fullscreen-grid-stills-container elements during playback onlyytp-grid-scrollable and ytp-fullscreen-grid-peeking classes that trigger scroll-based recommendationsended-mode class and video element properties--ytp-grid-scroll-percentage and --ytp-grid-peek-height to 0 during playbackCompatible with both old and new YouTube UI versions. Compatible with both Firefox and Chrome.
UPDATE SEPTEMBER 2025. Update your script!!! The “scroll in fullscreen” mode you remember is gone from YouTube’s codebase. It was a hidden feature flag (toggled by the deprecate-fullscreen-ui attribute), and removing it would revert you to the old branch. The script has now been updated to add the function back to the youtube video page.
