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

I hate this tool with fake downloading and pay needs.

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

Ce logiciel m'a permis de bien télécharger toutes les vidéos sur youtube. La seule chose à améliorer est la conversion immédiate en extension de fichier directement utilisable selon le type d'appareils

Video DownloadHelper is really a good stuff.

best video download tool ever.

best user friendly downloader app. happy to donate

Need better interface - Nothing intuitive. Ridiculously imperceptible-- Videos are jerky and jumpy ...the watermark is intrusive -

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!

This is a commercial product! Converting costs real money, and the product does not recognize the 4K formats in spite of a lot of settings. Just compare with Flash Video Downloader and see what they find on YouTube videos, but the worst thing is scrounge the money. Install an additional file with codec and converter, because you will not download anything.After you install it, you will find out that you will download in an interesting format you will pay! Super! I lost only time, because stupid Mozilla can not distinguish paid offers!

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.

It takes a bit of getting used to, but it has become essential! Thanks, when I get some cash I'll make a donation
