とても良い。いろいろなサイトに対応している。以前はコマ落ちも見られたが、最近は無い。

very good 非常好

Great software which I use frequently. The only reason for 4 stars and not 5 is that it requires an additional piece of software to be installed to be able to download certain file types, but overall no the end of the world.

Used to work great, now demands you download an additional piece of software, which makes it basically pointless. If I wanted an extra piece of software to download videos, I would've looked for that in the first place rather than going for an extension. I would've given it 5 stars before this problem, which seemed to start with the latest update

This works where many other extensions do not.

TERRIBLE! Forces you to download extra software and puts an large ugly QR code in the corner of the video!

The best app

it's good

After this last update, it started adding a massive QR code to videos.

Will handle any video file if there is any file to be found. Good speed, good options, Great primary or backup downloader.

El mejor add-on de firefox para descargar videos.

Extensión muy fácil de usar, permite guardar el archivo en varias calidades segun el video que se desee descargar, recomendada 100%.

Quero usar o conversor agora.

このAdd-onは本当に使いやすくてストリーミングもダウンロードできてMP4も安心して選べれるのが良いです。

必须好评；Firefox是最好的浏览器；而对我来讲，有一个download视频的App就超重要

the best.

Excelente programa, fácil para usar y funciona a 100%

I have used this for a long time now and it hasn't failed me yet. on Linux as that's the only safe operating system
