Excellent tool, easy to use; can't miss that big fat green arrow under the video! Works with current YT content, which is a lot more than can be said for other downloaders.

Perfect! Exactly what I was looking for. Makes other downloaders superfluous.

Good

Fast download, faster than others I have tried before, in seconds from the minutes of others. Many of the youtube downloading add-ons no longer detect the videos as they stream as ADP from the more familiar mp4, evidently a change by youtube maybe because flash will no longer be supported. More than pleasantly surprised to find this extension that works with the dominance of the current format of videos streaming on youtube.

Very useful extension, but, unfortunately, stopped working in Yandex.Music. :( Very sad.

Best extension ever. Now I'm able to download YouTube videos with much ease.

complicated i think this addon is very simple and very good just click download
