I was using this extension from more than 7 years. It's really fantastic.

Funktioniert tadellos, besser als alles andere, zuverlässig und schnell,... topeinfach, einfach top! ...

Muy buena...

Good

Works really well with Youtube. :)

It properly enlists what is on the Youtube website. The best part is to download the Audio-only file which was one of the features of Flashgot, but not working in Quantum.
Thank you

That is the best

使いやすい、わかりやすい、動作も機敏、すばらしい。

Easy use, easy understand and Quickly, so good.

It works well on all videos I've tried and with ease! Also, I love the media converter and muxer.

works perfectly, i love it!!!

Best youtube downloader of all the similar extensions...it can choose the highest revolution version and download it.

Now i can update FF

good enough

Works well! Easy to use and fast to download.
