This add-on works as mentioned and it's very easy to use. Of course, it fails to download at times (just like other YouTube downloaders), but works faultlessly most of the time. What I like most is the attitude of the author--always positive, sincere, and cheerful. Every so often, when an update notification pops up, I'm reminded of that cheerful attitude! Kudos, and all the very best!!

Hi there. I have been using this add-on for a couple of years now and it is by far the best and most reliable one that I have ever found, very user friendly and no audio or video issues when the downloads are complete. It is great I can choose which format to download with for a better quality.
As long as you keep doing your good work on this, I will keep using it and recommending to all my friends as I am now. Thank-you very much for all your great work.

An automatic update today, rendered my down loader useless. I've enjoyed it for a long time. What can I do? Do I have to pay more money?

This downloader is very easy to use, intuitive and fairly fast. Thank you.

Most useful, splendid downloader. I'm using only this!

Perfect performance..!!

A great and well maintained add-on. Any problems are quickly seen to.
Thanks heaps.

So far the best !!!

This addon will pop up a new tab every couple of days while your trying to beg you for money, there is no way to stop firefox launching and going to this new tab, I've had virus's which were less invasive. Avoid.

Annoying popups every time it updates.

The new update is great, works again like a charm. Thank you kindly for your hard work.

always uptodate!

Great Add-On!! Works great mostly unless Youtube just changed code to block downloaders, then just wait a day or two for update and then works great again.

Very useful. Am fully satisfied
