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.

FINALLY!!!! this is the only addon that works.

works, but slow. the video name is "【#⁠湊あくあ5周年LIVE】Dreamy day 【湊あくあ/ホロライブ】", but the download file name is "⁠湊あくあ5周年LIVEDreamy day 湊あくあ ホロライブ"

Doesn't appear to work anymore. just opens a new blank tab...
