very good

I really enjoy downloading videos at home to watch at work or while traveling. After donating I am able to sometimes download in 1080. Easy to use.
Edit: I am dependent on this add-on for Firefox as it allows me to watch YouTube videos offline as well as avoiding all the ads that Google deems necessary for the CEO to make more money.
I support this developer and I hope you do as well.

May 2021, it works very very fine, I donate 3 times because i am grateful
thank you for your work

Its good just wish they had separated downloads for sound only and video only like one I had a long time a go. It was separted by choosing something like mp3 for sound only forgot all the format selections.

The easiest and most eye appealing. I just wish YT would allow HiDef downloads. This is the only YTDL addon that consistently remains installed on all my systems.

I do not use this add-on often, but it is useful when I want to download a video. It blends in seamlessly with the site, adding a download button. It also does not seem to add much in the way of overhead to the browser.

This extension has helped me replace a lot of the hundreds of albums I'd collected from 1959-1981 that my g'friend [at the time] had ripped off to support her habit while I was out of town for a year.
There is no other app that continously works as well as this one.

Thank you 'Easy Youtube Video Downloader'!

Since my Mac has acquired a pretty Chinese vocabulary, I've gone back to my MacBookPro I was using to watch movies on a screen on the wall, but want to add to my favorite youtube video downloader review that I couldn't have done any of that screen watching without the videos I downloaded through my Youtube Video Downloader app.
Thank you again and again ...etc

I have found this Youtube video downloader to be the best I have come across and am very happy with how easy it is to use. When I get a new computer, this is the only downloader I look for. Very happy with it.

Update Sept 29, 2021:
This developer is the best. He successfully works very hard and quickly to keep this addon working while YouTube frequently changes its code.

Original review from 2018:
For 10 months, I have been using the 'Easy YouTube Downloader Express' in Firefox (currently v61.0.2) on the iMac (macOS Sierra 10.12.6) without any problems. The downloaded video is always good quality. There are several great features this addon sports. Unlike KV 'All Video Downloader' you don't have to go to another webpage with the link to download your video. And unlike Video Download Helper, to select your download format you don't have to sort through a long drop-down list of various codec choices, mixed with lots of jpegs and with other media files. In this Web Extension (aka Addon) the choices for download are consistent from one video to the next. It doesn't require thought or promote confusion. It has downloaded videos the other downloader addons could not. I am very pleased.

This is really a useful tool that I ever seared for. It can download the video from youtube with a effortless and user-friently way! Great! Thanks its developers.

Works great, no fuss and updates are quick and effective.

Good! It works easily!

does what it says on the tin

I use a couple of different down-loaders. After around the fifth time my old primary down-loader wouldn't down a video and Easy Youtube Video Downloader Express did it became my primary and the rest are gathering dust. One of the best out there I highly recommend it.

I like this add-on for Downloading Videos, But HD Videos not able to download from it. Thanks

Easy to use, exactly as I needed, which was to download short instructional videos from Youtube so I can view them without internet if needed. For this purpose, I don't need particularly high quality downloads. Creator also keeps add-on up to date.

Es muy fácil de usar y muy útil

I have been using it for some time now. The add-on always worked without problems, is super easy to use and totally unobstructive ( meaning it does not clutter the layout of the page ) no adds. I like it.

It has become harder and harder to find a working YouTube video down-loader but this one works extremely well. There is a choice of download type and size which I find really great, just downloading a sound-file is all that is needed sometimes that saves time and money. It's easy to install and operate and it works! It is worth the little donation to continue using a great service. Cheers

Works very well...excellent add-on that works!
