99% reliable. Much better than other similar addons.

Very nice, helpful , faster and easy to use

This extension has been incompatible with Firefox and, apparently, Firefox-based browsers--Tor, for sure--for several updates now. Does it download? We will never know, because the VDH menu is unusable. It's all squashed up against the edge of the screen, overlapping itself and unscrollable. Yet Mozilla says it's "recommended"? How is that possible?

firefoxには必須です。最強

Comodissimo per salvare video su pc altrimenti non scaricabili. Sarebbe comodo se si potesse aggiungere un alert quando si tenta di chiudere il browser a scaricamento in corso.

Every time I donate every 5 minutes it keeps asking for more donations.

Muy bueno para descarga de videos de facil y simple uso.

Es muy bueno y eficaz

Perfect for downloading videos.

This video downloader app is easy to use and work on a multitude of sites. Very impressed!

非常好的一个工具，在线学习视频可以保存下来看了

very good

No matter what I do, the add on just opens another tab that says 'no media to process in this tab'. The desktop add on works perfectly. The Android one, I cant work at all. There's a license section. i pressed 'get a conversion license, but nothing happened, so after a while I gave up. There is definitely a severe malfunction, probaably on my part, but the add on gives no clue.

Thank you, Mr/Ms Developer for expertly keeping up with security updates and video format changes. No other extension or app can do as much is this one to the best of my knowledge. Vimeo and YouTube keep on changing their formats and VideoDownloadHelper works his magic to make the program work without much effort on user's part.

Program runs well on a 14 year old Laptop running W7 with 2GB Ram and a Pentium Duo processor. Also runs well on a Mac using High Sierra and i7 and 32GB Ram.

I've tried all the extensions to DL video and always come back to this one for it's simplicity and success rate without intervention on my part.
