no matter which kind of download you chose, you always get a lame excuse about changed youtube formats and are urged to pay for the full service. Hence this is not a free addon, it's payware.

need to pay for using this app! not recommend!

Absolute trash, doesn't download past 720p unless you "upgrade," doesn't support 4k download in any context. Garbage.

Works well, thanks to programmer.

The best I have used

This is an extremely useful and easy-to-use extension for Firefox that I use all the time (especially to extract sound files from music videos on YouTube for tracks which I haven't been able to find on the streaming services I use). I haven't had a single issue with the app and I highly recommend donating to the developer so that you get unrestricted use of all features.

I like that tool, is simply and fast dowloder , i use it for music video clips and some funny videos. Thanks Guys for the wonderful job !!

Only allow download of videos that have been already downloaded recently by a paying user.

Estoy usando la app y pare estar bien documentada, eso es algo que apresiamos y buscamos en la web

Worked well until all of a sudden it starts asking for money. Refuses to download 1080p.

Прекрасно грузит .

They ask for money for something that is not real. Any other YT downloader dosn't have this problem.

a fuerzas te quieren hacer descargar aplicaciones, pesimo servicio

MP3には第3者のアプリがいる。

fine tool to get mp3's - works like a charm; my latest use is some months ago; not working anymore for me

Is only willing to download at 360p, and tells some lie about how the conversion "needs powerful server infrastructure". No it does not. That is a flat out lie. It should just do the conversion on my machine. Absolutely ridiculous.

Someone else recommended a software called Jdownloader. It isn't as convenient as a browser extension but it works pretty well.
