This has been one of my go to add-ons. It has been reliable and it goes above and beyond in adding sites and adapting to changes. Just remember the internet and especially sites that provide video content changes continually.

使い勝手が良い。ダウンロード不可の場合でも原因の把握が分かり易く、対応に困惑することが少ない。

Very helpful and works on most of the websites. I only give 4 stars because when you download more than 1 video (what I normaly do) and 1 download fails there is only displayed that a download has failed but not which one. So I habr to check the downloaded files which one has smaller size as expected or in worst case I have to open each file to test if the video is complete. If the name of the failed video would be displayed the addon would be perfect

voilà un utilitaire indispensable! Bon, Youtube n'est pas toujours téléchargeable, mais très vite, une mise à jour rétablit ce dysfonctionnement transitoire

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.
