I have downloaded 100 video using video Download Helper and it is best tool available at Mozilla Firefox. I didn't had enough money with me to donate for this tool. One who have surplus money do Donate as this is the best tool for video download.

This plugin works well and can download many types of video that other plugins can't find. But it need extra software installed especially if you use Linux. Need better manual for it.

hält was es verspricht und tut was es tuen soll. unkompliziert, sehr gut

Un programma che finalmente permette di scaricare i video da Internet e che dà soddisfazione. Permette di convertire i video nei diversi formati più graditi subito dopo averli scaricati. Assolutamente consigliabile per chi usa Linux, ma anche per altri sistemi operativi assieme allo straordinario S.O. Firefox che uso anche sul mio telefonino.

useful

Great add-on app. Easy to use app to download videos. Download speed is fair and can also download limit up to 5 videos but, I think it also depends on the owners PC. Enjoying it so far using this app for my video library.

很好用

Exactly what I needed. Yes, anything above 20min gets a watermark but everything functions as it should.

First you have to install a third party software, then the app put a watermark the video with QRcode and ask to pay a licence. This si scam.

Excelente ad-on, fabulosa para guardar videos de una gran variedad de sitios que otros programas u otros ad-ons no pueden. Recomendado 100% (comentario actualizado)
