Maybe if you upgrade to pro, else pretty useless...

Absolutely helpful – I've chosen the extended version (available with a donation) and highly recommend it! Update: developer actively supports this extension even when necessary very fast – worth paying for it every cent.

works perfect for me with video.

One of the very few downloaders that actually work. And not trying to trick you with malware.
And also gives you a fair chance to download popular pieces for free.
And even downloading everything else is available at a fair price ($10).
Dishita is constantly working on it to keep up with YouTube changes.

Works great! I've used others but they eventually quit working. I've never had that problem with this one.

Epic, first thing I add on when I have a new ff install.

very easy to use

Great add-on. Very easy to use and constantly updated to keep up the pace with Youtube changes, Thank

This is an awesome plugin. It has been working well for me for many years. Thank you

This add-on works perfectly well on downloading Youtube videos. I use it to keep videos of my favourites artists and it is great.

Works perfectly every time, exactly what it's suppose to do, thanks guys!!

Works first time. Reliable and easy to use.

Great addons

It's a very good and simple downloader; I have been using it for last 3 years. The only downloader which can download 1080p resolution from YouTube. Good job!

The best tool I have found for this work. Thanks!

Smooth, easy and without complications, I get the download almos 99% of the time, so it was with the free version. I hope to get 100% with the pro version.

Easy to use, simple interface, user friendly!
Highly recommended.

Does exactly what is intended!

a very useful addon
