very good

Seems a very straightforward add on that works really well so far. Very pleased with it, thanks

Works well! Other programs did not work with youtube 12.27.22. No issue with yD.

As an amateur archivist, this is an important part of my toolset. (YouTube-) source quality video files of my choosing depending on my needs. Some parts of the user interface / experience are weird or counterintuitive, but overall this is great.

Doesn't tell me I need to buy anything or upgrade in order to use it.

Wow!
Superb and cool app!
I got this so much useful!
I love it!
You should use it if you haven't.
Great! I can't say anything bad of this addon.
It's the best!
