Best Youtube Downloader! Rated 5 out of 5 stars

I love this addon!!!
Its the best Youtube Downloader i found.
Really AWESOME ADDON!

Cuts Short Rated 1 out of 5 stars

I loved the concept, but this add-on must still need some work. It cuts the audio short every time, every video. Yes, I made sure it wasn't the video itself. So, this makes this utterly useless for me.

Superb! Rated 5 out of 5 stars

Quite reliable -- broken download links have been fixed -- and very easy to use. The best addon of its kind!

Useful and user-friendly Rated 5 out of 5 stars

Easy to use, works wonderfully, provides multiple options for saving videos. Free to use, but also well worth any amount you care to donate--it's all well deserved.

Problem fixed Rated 5 out of 5 stars

Works fine now, thanks. Only downloader you will need, simply the best.

Error - cannot connect to the signature server Rated 5 out of 5 stars

I really hope the developer can fix this error as it's hands down the best app - I went on to github where there is mention of version 0.5.7 but Firefox prevented this from downloading, talk about frustrating.

Awesome. Thank you! Rated 5 out of 5 stars

Works like a charm. If you want to grab 1080p videos, just follow the prompts, install ffmpeg and Media Converter and Muxer and it will work.

Brilliant! Rated 5 out of 5 stars

Simply the most honest -no crappy ads/offers/nags - and efficient, versatile video downloader I haver ever used. And I have tried at least a dozen! Probably the complainers did not take the time to install FFMPEG correctly...
