About this extension
This extension fixes a problem where YouTube's fullscreen mode stops you from scrolling through comments and related videos.

What it does: It removes a special code that YouTube adds to elements that breaks scrolling in fullscreen mode.

How to use:

Install the extension
Go to YouTube
Watch videos in fullscreen mode
You can now scroll normally through comments and related videos
The extension works automatically. No settings needed. It only works on YouTube and doesn't collect any personal information.

This solves the frustrating issue where you can't scroll in YouTube fullscreen mode. Perfect for watching videos without interruptions.
Developer comments
YouTube’s player is a moving target. Releases land after targeted testing, but breaking changes from YouTube can still slip through. If you spot a regression, open an issue with the video URL and reproduction steps.

Release notes for 1.0.75
  • v1.0.75
  • Introduces a debug mode (enabled via URL param) with logging, metrics collection, and a 'Save Log' button for diagnostics. Refactors and enhances fullscreen control bar scaling and style restoration, ensuring better compatibility and maintainability.
  • Refines the logic for applying control adjustments by introducing synthetic resize scheduling and flags to prevent redundant resize events. This helps avoid unnecessary reflows and ensures more reliable UI updates.
  • Introduces a double-click event handler on YouTube video elements to toggle scroll mode, improving usability in fullscreen. Also updates window state handling in background.js.
