Does what it says on the tin - exactly what I and probably you needed.

This "is" the only YouTube down-loader that works presently. However there a couple of issues that I've run into that need to be fixed: (1) it doesn't work for downloading music videos in MP4, and (2) the orange download button disappears occasionally and you have to refresh the page to get it to appear...

отлично качает высокое качество, проблем ни разу не возникало

Only works half of the time, doesn't download better than 360, and lags Youtube like crazy. Still better than all the other addons which are currently not working at all. Still, even with t being the only one that sort of works I can't justify giving it more than three stars. Fix it please.

OK

Сколько качалок перепробовала, а эта работает почти всегда.

Super
