Video DownloadHelper is very efficient and fast, it helps me so much every day.

The Linux version of this works perfectly. The fact that you get a watermark if you use this add-on under windows is the reason I'm only giving 4 stars.

使用簡單，有效。

This is an excellent extension for firefox and it has helped me so much when i need to download a video from you tube or other video sites.

ottimo....non scaglia un colpo

Very useful to download videos from any website! Even pluralsight videos can be downloaded with this addon!

accessible to music

good

Awesome!!! Works great with everything I try to download. Would highly recommend.

Ich habe dieses AddOn als sehr brauchbar empfunden. Habe noch nicht alle Funktionalitäten ausprobiert, aber die Bedienung ist problemlos und das Herunterladen klappt fast immer.

Efficace, flessibile, semplice ma funzionale. Bravi.

Me parece una herramienta muy útil, la utilizo a diario

Ottimo, funziona perfettamente, consigliatissima

A extensão Video DownloadHelper é simplesmente sensacional, possibilita a gravação de vídeos diretamente da internet e evita a perda de conteúdo pelo usuário. Recomendo a todos a utilização do Mozila e das extensões do programa. Nota 10

最最好用的下载体，太好用了。谢谢你们

I have installed this addon, then I had to install required desktop software, I waited for many minutes of "aggregating" (twice - 1st time for... I don't know what, 2nd for downloading), and finally I have blurry video with QRcode. Great.
