Turn Autoplay Off on YouTubeΒΆ

When you're on the YouTube website, go to a video page (for example, this one) and then look for this interface item somewhere on the right side of the page:

../../_images/autoplay-on.png

Click the blue toggle button so that it looks like this:

With Autoplay disabled, you don't have to worry about another video automatically playing right after you've watched the current video.
