Downloaded the video twice, but there is no sound!

Відео "S.T.A.L.K.E.R. 2: Серце Чорнобиля — Трейлер «Час Можливостей»" в 4к завантажило як треба, тож 5 зірок, сподіваюсь і далі так працюватиме, а головне - безкоштовно.

Links to a website, and nothing more.

That website produces a totally white screen, but does start the download. However, it doesn't say that it's doing that, and the download doesn't say how big it'll be (no percentage). This is bad hosting practice on their end.

Therefor this will get more stars if it's better integrated, gets better UI, and shows any type of progress.

does not work. mp4 downloads lead to a YouTube 404 not found page, and webm downloads lead to a mysterious and suspicious blank page.

解析用网站下线，点击按钮之后无法下载

provoque de sérieux problèmes de lecture sur certains fichier quand les tag ID3 sont modifiés, sinon très bon module

No encuentra los enlaces correctos. Y te baja la publicidad. Inútil.

Not detecting videos at all.

Doesn't appear to work properly anymore: only offering 320p and video length of 5 minutes only. Even if I go directly to youtube4kdownloader.com and paste in the video url.

very good

god

I have just tried this add-on with a few videos so far it works great.

No longer works. Goes to a Secure Connection Failed error...

Throttled so severely as to be useless.

it's working just fine, I've tried several similar extensions and decided to continue with this one.

Doesn't work with membership videos.
