This does not work for Firefox on MacOS Big Sur. it downloads the video with no title and the file is unplayable by any video player.

Youtubeのダウンロードに、とにかく時間がかかる。わずか数分の動画に対して、最低でも、その数倍、下手をすると10数倍以上もの変換時間がかかってしまう、しかも、その間、CPU使用率は１００％（CoreI７　８コア）。以前はそんなこと無かったのに、、、CPUのパワーで一体、何を計算しているのか？？（動画エンコードと見せかけて、マイニングでもしているのでは？と疑ってしまうのは私だけでしょうか？　それとも何かのバグなのか？？）

No me ha gustado que se añade una marca de agua en todos los videos descargados y te avisa que hay que pagar para quitarlo una vez lo tienes ya instalado... Hubiese considerado pagar, pero estas formas no me inspiran confianza. Hay otras alternativas gratuitas

used to be good, now it's all about money, and it doesn't work perfectly like it used to.. i hope they get better and as good as before

helper will not work properly, i have removed and reinstalled. but not working

DID NOT WORK

Why do I need to download a desktop app. That's pathetic.

I can NOT save any video from yutube, vimeo

I am not able to download anything, using this app now. I use to though

REQUIRES DOWNLOADING ANOTHER APP. Sorry, don't trust anybody that says they have a so and so if you download it, then when you do download it, expecting to get what it says you'll get, only to have them say, oh wait, you need this also. No mention of having to install more than one add-on to make this work.

It used to be perfect, but now it terrible. It is an impossible to make any download no more. Forget it!

With the QR-code stamped on each download, this thing lost its legitimacy. Please stop recommending it. I don't pay for Firefox, why should I pay for an extension? Especially on the pretense that I am to honour the developer who works in my interest. Whereas he clearly does the opposite: reduces functionality to make me pay. Uninstalled. – P.S.: Suddenly, a wave of five star reviews for this addon. Obviously fake ones.

The Video Download Helper used to be a great app/extension, but now it's terrible. I loved the earlier versions of this app. Now, I'm seriously considering deleting it for good.

Dosen't work with you tube. Only the 1 week soemtimes. Every time collecting data failure

Trash

don't insert watermark:(

Просит денег иначе ляпает QR код поверх видео...
