This is a really good extension!

it works

Excellent service, very helpfull and I like it

Works fine, easy to use, fast updates after youtube code changes that harm functioning of the addon.

A really useful, easy-to-use system!

This addon provides a unique opportunity at a challenging time, in that it is helping independent filmmakers like me produce new work during our strict, but necessary COVID lockdown in Melbourne, Australia. As we are unable to shoot on location, I am finding YouTube one of my many sources for inspiration as we expand the genre of 'recycled cinema'. Supporting independent developers so they support us isn't that much of an ask. Go the PRO version and use it wisely, carefully.

These folks are in a constant cat and mouse game with YT to give you this functionality and they're doing a great job. For me, this add-on is a special blessing because I mentioned G-d in my videos, upon which Adsense canceled my account and YT froze me out of my channel account. Thanks to these kind folks, I had a way to download my videos in 1080 HD.

This is by far the best YouTube down-loader add-on that Mozilla has. As a long-time user of Firefox, (since 1998), I know what I'm talking about. Kudos to the coder of this extension!!

Easy, very usefull, no better alternative
