Although when downloading it uses a lot of resources (using low end pc) it will download every video from every site! After downloading more than 100 video's, not a single one failed!
Best video download add-on I ever used!

the best app on the matter

Awesome ! very Usefull

Amazing add-on I can now get my hands on the best anime without relying on torrents. Works great for clip montages when the clip-source does not have native downloading.

Exelente herramienta de descarga.

Sehr hilfreich in dieser Zeit Tutorial-Videos zu sichern, bevor diese verschwinden.

Thanks for it !

Video DownloadHelper just keeps getting better. Gives great results downloading from virtually any website.

Love this tool. It is so easy and convenient. I use it a lot to keep a recording locally of the classes I attended online.

Erledigt die Downloads sehr zuverlässig, es gibt mehrere Optionen als Video oder Audio zur
auswahl, die Dateien sind mit Youtube-Namen versehen.

very helpfull
