Somehow Google felt that this wasn’t worth mentioning, perhaps because they have more pressing matters at hand such as the lawsuit against Viacom, but this new YouTube feature didn’t escape the notice of long time Google blogger Alex Chitu of Google Operating System. It’s possible you have noticed it too.
When you right click on a YouTube video you will find a new option “Stop download”. Clicking on it will stop buffering the video. So why this is a good feature? Because it allows you to stop a video from downloading midway.
When you open a YouTube video page, it starts downloading the video immediately. If you open 10 YouTube pages all 10 videos will start downloading together. Now you can prevent this.
Another use of this option is if you are interested only up to a certain part of the video. As soon as you’ve seen what you wanted to see, you can stop the video from downloading the remaining part without having to close the page.
