The free version of the add-on is easy-to-use, fast and reliable, even with (very) long content. Ideal integration into YouTube's interface.
I bought the pro version with confidence since it seemed so robust, and I was not disappointed. In a minute I had seamless access to HD download, which is as easy and fast (considering the higher volume of the files) as the regular version.
I haven't found any cons or flaws yet, as far as my uses are concerned.

I've used several YouTube Downloader/mp3 converter tools, but this one is by far the best! It uses a 3rd party website which is really key for it's performance. It is really fast and can handle many downloads at once. It doesn't directly download the video file when making an mp3 conversion: so it's great for metered connections! There's a small fee for using the website payable up front, but it's so worth it in performance! So happy!

I've been using Dishita's Easy Youtube Download for many years now. It's effortless to install, easy to use and consistently reliable. Whatever else it may be, Youtube is a huge storehouse of music. My work depends on access to a wide variety of music recorded live or in studio or from film, radio or TV. My research would come to a dead stop without the ability to download music for study. Years ago and after long hours searching the internet to find a reliable, inexpensive and easy to way to download from Youtube, I finally found Easy Youtube Downloader here on the Firefox add-on page. I downloaded it, made a small donation and after a couple of initial minor bumps that Dishita promptly and clearly helped me over, I had a swift and efficient way to download from Youtube. At relatively long spaced intervals over all these years the service has been interrupted when Youtube has changed its design. When this has happened, I've been able to return to the Easy Youtube Downloader installation page, follow the simple instructions to install Dishita's latest update and I've quickly been able to get back to work. Bravo Dishita! This add-on's a boon to everyone who needs the ability it provides. The original idealistic dream for the internet was that it would open to everyone the world's wealth of art, thought, knowledge and communication, easily and cheaply. Now that nearly everything online has been commodified to make the very few very rich at the expense of the many, very few people and services have survived to continue in pursuit of that original ideal of easy universal access. Easy Youtube Downloader is one of these few survivors. Install it, make a small donation to keep the service going and then thank Dishita for keeping a huge portal into some of the world's riches open for us all.

Works well. Nice add.

AWESOME :)

I've paid another donation because I find this Add-on handy and I use it regularly. I can view the video or listen to the sound track a second time if need be without connecting to the internet which saves on download costs. Plus some times of the day the download speeds are incredibly slow making it almost impossible to watch video.

I'd just like to add that I after an update the Add-on wouldn't work properly. Anyway I contacted Dishita and now its working a charm. Thanks Dishita

The best of the best add-on! it great works.

It's a very deserving add , If get some problem , It's handled very quickly . Recommend to sponsor this add .

This service is absolutely amazing. I donated money, and honestly didnt know what to expect of if it would even work. But it did! And i far exceeded my expectation on how it would and should work! Thank you so much for whoever made this service possible! I will absolutely recommend this add-on to all my friends and tell them to review this add-on as well! Its worth every penny and you have the option on how much you would like to donate.

cool

Excellent downloader, HD and SD looks nice on 133inch screen.

Indispensável

Work with waterfox 56. thanks you.

Add on is as good as can get so if you cheap out and only give the minimum and are using the guts out of this program then shame on you!!! Man or Lady up and pay the 30 dollars as its well worth the spondoolies(money)

great app for MP3 download

Awesome! After some frustration with other apps that implement a watermark in the vids this is the real thing!
Great stuff and just as you expect it to be!
