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.

Good on. I have used the old one for years. This one needs (more correctly, I want) two tweaks. Firstly, let us specify the directory to save the original video file in. We have the option for the converted audio file but not the original video. It always goes in Downloads. Secondly, let us specify the path to ffmpeg rather than install another copy. Most of our systems have ffmpeg already, just verify the path. Thanks for the good product. My grandchildren love mp3s that I get from the Youtube videos.

ottimo programma

works perfectly, i love it!!!

No support for 1080p.

Works well, but doesn't download fullhd or higher resolution videos.

keeps saying youtube signatureLocal: Cannot resolve signature;2

unable to download anymore

No longer works as of 14.02.18 gives this error, "youtube signatureLocal: Cannot resolve signature;2", I changed nothing I downloaded videos last night, I try today it gives this error I was even using the old version new version none works no more.

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

Quick Download button does not work like it used to be after Firefox Quantum update. It doesn't download 1080p anymore. It doesn't download m4a audio files either. Very frustrating to see such nice apps go bad. I had to switch to a stand-alone downloader software.

I wanted a simple downloader compatible with DASH that did not rely on 3rd party websites and/or PRO payments to do its work. I already had FFmpeg, so this was fairly easy for me to set up. Once set up, in two clicks I can get correctly muxed DASH videos in my download folder. Maybe if you don't know what nodeJS or FFmpeg are it sounds scary to install? Firefox runs a batch file, the batch file executes nodeJS, which executes FFmpeg.

A download button in the YouTube player page would have been preferable(but susceptible to Google messing up the layout), but the standard addon button isn't terrible.

Now i can update FF

Addon is broken.

Very slow download speed opus format!!!!! (50Kbs)

good enough
