How to hide the \"more videos\" section in Youtube iframes, when the user stops the video?
Example:
I'm using Firefox with the Addon uBlock Origin.
Click on the logo of uBlock Origin and click on the settings icon, to Open the dashboard.
In the dashboard, go to the tab My filters and add this line:
youtube.com##.ytp-scroll-min.ytp-pause-overlay
Click Apply changes.
Now you won't see 'More video's while pausing a Youtube video.
