I didn't write the following, but I agree wholeheartedly with every word.
"This works extremely well and the developer is constantly updating this extension to ensure it keeps working despite the constant code changes from Youtube designed to break utilities like this. A truly excellent extension with top tier support. Many thanks Dishita".
Couldn't put it better myself! It's a great extension and one of the few that is constantly being updated to meet the challenges of Youtube. Highly recommended.

This is a great add on. So simple to use and has great resolution options. You really don't need 1080P to watch a video on your tablet!

Superb application and constantly updates in response to OS changes.

It works wonderfully, and whenever Youtube changes their code, it's updated to work again just like that. The man is on it!

First class add-on. When YT changes the code this developer fixes the add-on within a short time. People who vote one star should exercise some patience and gratitude for what this developer does for us over and over again every time the goal posts get moved.

The best piece of software I have without any doubt! If you want or need to download Youtube HD video or audio MP3 256k this is it. The only software that works and most importantly it is updated asap. Even though Youtube tries to make things hard.

P.S. If your really stupid, like anyone who rated it 1 star just go away. The world would be a better place without you! Just try and find another product like this.

Still doesn't show download button for some youtube videos if this can be fixed I would give 5 stars.

I am very happy with it as it is very easy to use and the downloads are very, very fast.
I want to continue to use it.

An awesome add-on, works very well, probably the best YouTube downloader out there.

Great add-on, I've been already several years downloading videos with it,
It fails every few months because of changes in Youtube, but it is usually fixed within days.. Thank you

The developer is still around and he's working on fixes for everything, so don't despair!
