Very nice add-on, especially as it allows downloads of better quality. As YT changes its codes from time to time to try to block downloads, this add-on is usually very swift in updating its own codes so as to allow its users to download again. Just need a little bit of patience and you can download your files when the updates are installed ;-)

The best of the best

Excellent and nothing comparable . Very fast and reliable. You won't believe unless you try it. I love it. Thank You So much.

Great addon to Firefox. Downloads are good quality. I use it to download video's which i know or suspect to be deleted by YT. Happy with it.

Always up to date, and a really good downloader. Thank you!

I have used this down loader and it is excellent despite G's best efforts.

Good downloader and easy to use thanks

Two things that I love about this addon. It is simple to use and the author updates it to make it work with the latest Firefox version. Thank you! I love you! (platonically)

Good downloader and keeps upto date, except need premium to DL 720p or higher

This add on works well most of the time. YT changes their codes frequently and download developers have to react which takes time. This one gets the job done, just stay with it.

The best downloader for me at the moment. The people who made it also constantly work on improving its perdormance especially in the hostile environment, you know what I mean.

This addon works perfectly. The developer responds quickly to changes in the youtube code. Highly recommended.
