It's a great addon to have. It quickly and easily identifies streamed videos that you can download. I like that it can download the video in multiple formats and different file sizes. I like quick download feature which lets you download without specifying destination hence you can quickly go through videos you want to download and not have to waste time setting the location for those videos.

下载视频的神器，非常好用，不过FF版比Chrome版更好用

Excellent. It can identify several video protocols and download all of them.
Grade A+!

Video DownloadHelper is really a good stuff.

best video download tool ever.

best user friendly downloader app. happy to donate

The downloader works for all kinds of websites, not just youtube and twitter. Since it also doubles as a converter, i can download videos as mp3's, saving lots of time compared to most online converters. I use it for all my computers. An absolute must have! ^w^

does as expected... keep it up!

Very useful add-on. Allows you to download videos from a variety of sources. Easy to use; not intrusive and does not hinder browsing experience. Would recommend to all.

Magnifico, descargo mis vídeos favoritos y los veo ofline cuando tengo tiempo.

Able to download videos from most of the sites

Ein survival Werkzeug der besondern Art.
Unerlässlich für jeden der gern Musik hört oder Filme schaut.

Excellent!!!

Nefis bir uygulama. Çoook işime yarıyor

If i could give 10 stars i´d give them.

The greatest thing ever for video downloading. I have limited bandwidth except for a free zone from midnight to five AM. With Video Downloader I can download, instead of streaming, to watch later. Thank you thank you.

بسیار عالی و کارامد

Consistently one of my favourite and most used of add-ons. Works with streams too, and lets you pick where to put your files and allows for conversion too. Thank you "mig"

Video DownloadHelper is an excellent app. It's never met a video that it can't download. I highly recommend it.

This application allows download from almost any site. With minimal effort. Amazing
