Youtube New Layout Rated 4 out of 5 stars
It seems the functionality of the download button is no longer working recently because youtube changed their layout which is probably what the plugin looks for to decide where to place the download button.
I have used this without issue for a long time and I am sure the developer will confirm with us that he is looking into it and provide us an update soon.
