YouTube's Annoying New Feature

A couple of days ago YouTube introduced a bar along the bottom of the page and it automatically plays all your subscriptions unless you manually shut it off every time you watch a new video. And it stays at the bottom of the page and pops up if you mouse too close to it even after you shut off autoplay. It was so annoying. Yes, was. Here is how you can get rid of it.

Update: YouTube is in process of changing the bar. Autoplay is disabled by default and the bar will not pop up unless you click on it. Good news.
