First it asks for a "companion app" to download videos. Then it says you can use the browser, and if you do it downloads a .js javascript file. Look elsewhere.

Best one!

excelente extencion muy recomendada

This is the worst most unreliable software on my PC. It most often refuses to recognize and therefore record a video. Sometimes after 4 or 5 attempts it will record, often without sound. This thing, in my experience, is a POS. I wish I could find one that works.

Esse software é perfeito. Consegue identificar, baixa e converter qualquer video. Recomendo muito!!!

Please optimize this extension for Firefox Android

Es una excelente aplicación, es increíble la gama de oportunidades que brinda

very good add-on. easy to download, specially with companion app

I've had extremely good luck with Video DownloadHelper. I'm impressed at how it's gone on working through browser and website video upgrades.

Excelente, me ha servido por años y años.

用户体验非常好！有时出来的视频选项过多，因为有广告，如何屏蔽广告，会更好

It does what it´s supposed to do and that also on sites where (many) other tools fail.

very good plugin

一个英语单词very good

отличная компактная и удобная в работе

The tools that do come with it sometimes work. Most of the time, there's no audio to accompany the video, which makes no sense. On top of that, downloading from some sites or formats opens a new page, asking me to download an extension on top of this expansion. Red flags there and a big no thank you from me.
Clunky, barely works and attempts to install more on your PC.
I tried it for a year, but no longer see its value. Uninstalled, awaiting something better.

very good plugin

This the best video download helper on Firefox, which is saying a lot because I love Firefox. Yes, there are still some bugs, but I expect to see them fixed soon. Otherwise, can't praise it enough.
