I've used this add-on for about 10 years. As YouTube evolves, some of their videos can no longer be downloaded with this add-on, but it's still good to have, and they do update it from time to time. If Download Helper can't download the video I want, I use another add-on or method, such as Easy Youtube Video Downloader Express, or I use VLC media player, or any other number of methods. DownloadHelper is a good and old tool in my digital toolbox, although it certainly can not do everything, and sometimes depending on how the video is downloaded, there is a watermark.

Najlepszy dodatek, bardzo użyteczny, przydatny i prosty w obsłudze:)

please improve documentation for bulk download in one click if multiple video link present in same page.

Es alucinante. Yo estoy descarando todos los cursos que estoy haciendo de varias Webs para poder revisar el contenido en el futuro. Per-fec-to.

Permet de télécharger et d'enregistrer pratiquement n'importe quelle vidéo à partir d'une page web.
Vraiment très bien.
