非常に便利です。
アドオン使用中のCPU使用率が100％近くになるのが残念ですが。

The product works great - you can go watch a streaming video on the internet and you can save it to your computer, so you can watch it all you want without being connected to the internet after that. However, it's kind of a joke when you're trying to figure out how to use it - it is so illogical (to me anyway, I'm only a computer geek) that I have had to reduce myself to just clicking things and seeing what happens. When it doesn't work, you just have to go back and start all over again. No biggie. It's not like I have a life or anything. Then, with no warning, they occasionally upgrade you to a new version that doesn't work like the one you had finally figured out, so you have to learn how to use it all over again. (They say "congratulations!" and inside you're thinking, well, I can't use those words in this review). On the plus side, it does exactly what you want, once you figure it out - you can save a video you're streaming to a file on your computer and watch it all you want later. Video DownloadHelper is very good at that, and as far as I can see they are head and shoulders above anyone else. That last bit is what truly matters.

很不錯的一個程式，使用起來很方便

good tyool. works most of the time

Quero agradecer aos idealizadores deste software/extensão do Mozilla, pois os downloads feitos de vídeos me possibilitaram melhor preparar aulas para meus alunos; Posso rever os vídeos off line (Em vários momentos não tive acesso ao ciberespaço). Muito grato !!

Great add-on as it works fine on most websites, but I have just one complaint: the pop-up content gets truncated due to the maximum width limitation of Firefox's overflow menu. Please make it responsive.

L'application rempli à merveille son rôle , toutefois elle ne détecte pas les flux vidéos sur certains site , notament les vidéo "flash embedded"

Ich finde es sehr sehr gut das es dieses Program gipt

sehr gut!

Video down loader is great! i use the downloader to get videos for my track team and videos for my 4yr old grandson. It is easy to use fast and free. I roccomend video helper to all my friemds and family.

ダウンロード先のサーバーの状態や制限などによる問題で速度や回線状況が不安定になる場合があるが、それらの影響を受けなければ非常に高速で安定したダウンロードができます。ただ、コンパニオンアプリについてはメモリの消費が大きいので使い方に工夫が必要な点があります。

good

I rate 4/5, because this is the best video downloader for any site out there. however, one problem that needs to be fixed, is that... when you watch a livestream through youtube, this plugin causes the video to stutter/buffer every few seconds and youtube becomes unwatchable. Every time i watch a live youtube stream, i have to disabled this addon for things to work normally. I've noticed that this add-on adds hundreds of items to the video download list during a youtube live stream, and believe this is what is causing the video problems.

Пользуюсь уже пару лет, единственный минус не все файлы с Ютуба может скачать. Но те ролики которые DownloadHelper'ом не качаются, не скачиваются и другими загрузчиками.

ease of use

不错，继续努力改进

ME GUSTA MUCHO LA APLIACION PORQUE PUEDO DESCARGAR VIDEOS DESDE CASI CUALQUIER LUGAR DE INTERNET Y FUNCIONA BASTANTE BIEN. SOLO TIENEN QUE MEJORAR CUANDO SE CONVIERTE LOS VIDEO QUE EL ICONO SEA MAS FACIL DE ENCONTRAR
