Video DownloadHelper has the best results of any addon I've tried so far, with about a 90-95% success rate. It can be a little quirky - sometimes it lets me pick which download method to use (which is what I set it to do) and sometimes it just picks one for me. I haven't really explored all the options, but it's worked well for me.

This program is outstanding for downloading videos there were a few bugs when they tried improving it but those were worked out and it is great!

My Android media player attached to my (big) TV doesn't list a lot of available YouTube videos like Firefox does, so I use Video DownloadHelper to put them on a flash drive. Now I don't have to sit bolt upright in an office chair to watch an hour of video - thank you

Great addon with a ton of known formats.

feine Sache

Having a tool to save short training videos has proven to be immensely valuable, especially when I want to review material on the move. Sometimes the list of file types and quality can be a bit confusing but I have managed so far. Highly recommended.

I've always loved Downloader Helper. It's so easy I just R click and point... and it does its thing. I just recently found it so still learning about all the available features.

I find this a very useful facility. I struggled slightly to understand how to use choose the options which are best for me - a less technical explanation would help - but overall results have been excellent. I rarely have time to watch/listen to things when they are on, so it allows me to save them for later and watch more than once if I want to.

自動動画検出機能にファイルサイズがついてるおかげで狙った動画がどれかわかりやすくＧｏｏｄ

love the easy to use it is. Also, the ability to download steaming file from a variety of site is great!

Une application géniale. j'aime bien

nice app, it solve almost all my video downloading problem

Muy buen programa , aunque tiene algunas limitaciones y errores con algunos videos , seria genial no depender de un programa a descargar para bajar algunos videos que antes se podia como si nada , fuera de eso todo genial

Sometimes very useful. Thank you very much.

Muito boa extensão para baixar vídeos na maioria dos sites e portais. As vezes demora um pouco, mas resolve.
