The best online YouTube video downloader. I have used this add-on at least ten years. You can download 1080p videos or convert videos to mp3 high bitrate files. If there is a technical problem, one gets a good e-mail support. I always get a reply if there is a problem with the add-on.

Es genial puedo descargar el video que quiera y en cualquier formato, buen trabajo.

This is a GREAT add-on. I'm an old Co-Lo Data Center tech & I almost never ever buy Xtra little software. But this YouTube DownLoader is absolutely one of the most useful and Xcellent working add-ons you could have for FireFox. I use it several times a day almost every day / all day Long.

It does 99% of things I wanted it to do. Support is excellent, I normally get an answer within an hour of asking for help. Highly recommended.

Great add-on. The pro version perfectly fulfills its function, so it is worth paying for it, and also contributing with its author for the work, time and effort put into developing this plugin and keeping it updated.

Fabulous add-on. I use it mainly to download tutorial videos into my Dropbox, and then I can view them at any time on any device. Works flawlessly, and support from the creator is excellent.

Good
