So far so good, it works. There is no 480p. And after a certain number of downloads, I got a pop-up asking me if I could give it five stars. I hope that the addon doesn't report home about who downloaded what, and the author doesn't keep a list of what people downloaded. Because if it was the case, it would be a problem...
I also downloaded the client appliction from the homepage, but didn't try it yet

Simples e intuitivo. Das extensões atuais para download é a melhor.

Good

I am very happy with this addon. My usual addon for downloading youtube videos is currently knock working, so I found this one and it works great! Highly recommended. Thank you!

satisfait

Works perfectly for me to download Youtube videos in a basic resolution (which is all I need for grabbing music to then later convert to mp3's), also love the nifty green bar that shows the progress of the download.

Very good

good download for me

very good!

super j'adore en plus tout est gratuit pour le moment , bravo à toute l'équipe

top!

Been using it for the last 24-hours.

As I require rips in 720p, I had to download the full UDL client in addition to the Firefox extension, but so far, everything has been perfect.

Server/download speed when converting is good, and once you get used to the way it works, I can find little about it to criticise tbh.

Worked for exactly two downloads. After that nothing works anymore

Love it. Works perfect. Youtube tried to shut us out but thankfully UDL is here. Appreciate you folks!

muy bueno

This Firefox add-on sorta works, but the full helper application is only available for Windows, and NOTHING except for 360 resolution works on Youtube. Selecting any of the "conversion" formats does totally nothing!
OK as a backup solution, but the old "Video Download Helper" is still tough to beat!
