挺好用的，偶尔会出现无法识别可下载资源的情况。

Really the best downloader out there. Love it!

Short version: They now add a QR Code watermark to your downloads so you'd pay for their software

Used to be the best, now you'll notice some "downloads" are slower, that's because it's actually downloading, then adding a QR Code, frame-by-frame, to your downloaded video, because now they decided that they will add the QR Code as a watermark to get you to pay for their convertor. Don't believe me? Hop on Youtube right now and try it. It used to be a very simple downloader as is, now it's unusable. Unusable unless you pay.

不错，很实用的东西。

Excelente

这个插件非常好，应大力推荐！

Does what it says; easy keeping instructions at hand!

Easy to use, works exactly as intended

Doesn't work. Requires separate desktop app installation that doesnt open on Mac even after allowing it on OS level.

Don't download: add qr code to the video and requires additional software installation and spends your CPU cycles to add an annoying QR code

这个软件可以下载视频流数据，很棒

If your Firefox doesn't detect Companion APP

Delete Firefox and install firefox.tar.bz2 archive from official site, this would fix the issue

it's workingu very well - thank you guys

very good~

Despite the fact that it needs a companion app, it is the ONLY (such) extension that has NEVER failed me! It works..!

Really strong and powerful tool, thx :)

I've downloaded dozens of videos using this extension for Firefox on Linux, and it works almost flawlessly. The only glitch is that sometimes the download fails, but if you catch it early enough, you can restart it and it will continue from where it was.

This extension flat out DOES NOT WORK. It asks you to install an external application, where the "install" button to install said application does absolutely nothing.
