Adds a "Stop Video" button under YouTube video which stops the video from downloading.
YouTube has recently removed the STOP DOWNLOAD command from right-click context menu. This script adds "STOP VIDEO" button right next to the Subscribe button. When you click on it, video will stop as it used to before.
NOTE : DOES NOT WORK FOR HTML5 VIDEOS. Chrome 32,for example, automatically forces HTML5 on some videos, in which case pressing the "Stop Video" button will only pause the video.
The same script is available in the Chrome Web Store, see Stop Video Download For YouTube.
