When I first installed the extension on Firefox, I was able to download 4K videos, but for the past several months it's been stuck at 360p on YouTube. I ended up buying a lifetime license for IDM, which is much better than this extension.

Doesn't work anymore, youtube not working among other issues

Doesn't work for youtube vids.

garbage, downloads without audio

Scarica file che poi non bengono letti o non legge la sorgente. pessima. Non supportatela a priori.

Gets to 100%, then stops- doesn't render .m3u8 on Android/Iceraven browser.

Видео с YouTube записывается без звука в браузерах Microsoft Edge, FireFox, в Яндекс вообще не доступно! Для Google Chrome обойти ограничения невозможно, потому что Google Drive запрещает скачивание установочного файла в обход его магазина. Загрузите установочный файл на другое облако! Потратил много времени на эксперименты, но звук на видео так и не появился! Пришлось найти другое расширение для скачивания с YouTube, которое было высокого качества и со звуком!

Does not download regardless of OS.

This sounded exactly like what I Unfortunately, it appears to do... nothing. There are no instructions as to how to use it, so I assumed there would be an icon to click on to download a video when watching. Nothing. No icon, it's as if the extension wasn't even added. I enabled it and gave it full permissions on firefox but it's as if it's not even there.
Sadly, I'm uninstalling and going back to my search for another video downloading solution.

Nie działa dla Netflixa :(

You can download only if you have copyright...?!? Really?

M3U8 files does not combine to single MP4 file.

And,ton of save button attack by M3U8 files when downloading.

It's too bad...
