This extension has worked perfectly for me on my older mac, and would recommend it to anyone. If I could, I would donate more than I did when I first tried it, but have been unemployed for over a year. IF my side hustle works, I'll add more.
Update: Have been using this for almost a year, and it's still great. In fact, gonna leave another donation for this developer, please consider donating as well!

So I've donate twice to this, and it no longer works for me. I've got the latest version, but no download button, and clicking the extension just gives a forever "downloading link" message.

Update (April 2024): Still using EYVDE and it is still great. Dishita stays on top of things and often updates. (2022 review: Been using EYVDE for years - by far the best I've found! And excellent support! Worth making a donation! Thanks Dishita!)

Software works fine and is easy to use. But sometimes I have to reinstall or do something else to keep using

Been using this for years....great app and does what it says on the tin...can't ask for more.

Great support

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.
