Best add-on, use it all the time and never any problem, big thank you to developer!
Update: after 6 years, still best add-on!

Very good, surprisingly fast and always there...right on the YouTube page that you're looking at, no app to open.

THE BEST

It just works!

Really like the extension, Please help support the creator to keep the tool updated. I did Has I feel he/she deserves it. Thanks.

Great Add On, quick and easy to use. I like how there's a big green download button on every video you watch on you tube and all you have to do is choose what you want to save the video as. It couldn't be any simpler to use.

I love this extension! It is so easy to use and much than the others.

What I like most about the extension is it's ease of use, you simply go to the video and you press the download button, I doesn't get any easier than that.

I love the easy way that I, a relatively inexperienced newbie, can download my you tube videos with ease, unlike some of the other down loaders that I have tried. It even works well with LInux.

This add-on is great. It simply adds a big green download button and has various quality offerings depending on the video. It would be nice to have higher quality audio downloads in the free edition, but that wouldn't leave much incentive for a pro edition. Great app overall.

very reliable downloader

This is probably my 2nd review. I've used this for several years now an it is the BEST YouTube video downloader I've ever found. No junk added, just the product. Get it! PS: as someone else stated carefully save the link in the email after paying for the upgraded version.

It's so easy I forget that it's an add-on.

Very easy to use.

great very happy with the extension thank you.

Very handy and easy to use! Given how much I use it, I was happy to make a donation as I think one should support independent developers.

This is a fantastic add on. I use it regularly, it's easy to use and works every time. Would highly recommend 5*

Pros:
Downloads Youtube videos very fast.
Easy to use because the access icon is always there right on every video page.
Interface is a snap to understand and use.
Cons:
You must very carefully save the link in the email after paying for the upgraded version that does HD. Fair enough, I guess.

This is easy to use, fast, slick interface, powerful.

And it is updated often and quickly after youtube changes their format, so that this addon will work again.

The paid pro version is wonderful for super high videos, well worth the money.

A helpful extension.

easy to use reliable and not too fussy

Love this addon easy to use and fast
