It really is annoying to be disturbed with Youtube's autoplay feature as it comsumes pretty much resources as well as power. Although we can disable this feature with embedded stop button but it comes to active whenever we restart the pc or browser.
I use Firefox and fortunately there is a solution among Firefox's addons. It's called as " Stop Autoplay next for Youtube" According to the developer, this addon blocks Youtube access to the autoplay module. Some user complain that it does not work at all but mine works flawlessly at the moment.
