Excellent, very useful add-on. Many thanks to the developer(s).

It is one of the best video downloaders

Works really well to be honest. Not as well with larger files though, which is why I have minus a star. The extension to the extension (or add-on to the extension) they have for larger files is giving me a hard time downloading for use, so I'll stick to shorter files (under 45 mins) for now! Great extension though. Saves me at work.

Useful in plenty of situations.

sehr guter Video Downloader

Globalement, Video DownloadHelper est une petite merveille car quand il s'agit de sauvegarder sur des sites complètement inconnus, l'extension se débrouille de manière formidable. Merci franchement aux dévelopeurs. Fantastique travail; Bravo !

Molto intuitiva e funziona molto spesso senza problemi.

Good when it works but it continues to disappear or stop working then magically comes back.

便利です -tube, -ver もいけました

I have only ever used this app and have no reason to change
