It's a nice extension. But the thing is that it can't convert any of the videos in any profile. It gets stuck to 0% after downloading it.

Yup, my first review on the site. I have to say, been using Video DownloadHelper for a few years now and it is extremely useful! A mus-have addon!!

es un muy buen complemento para musica pero para videos tiene sus hacks para saber utilizarlo

Do not get this addon. It leaves a qr code watermark throughout the whole video.

簡単！早い！無問題に良い物です。最も簡単なダウンローダーです

I enjoy using Video DownloadHelper. It's easy to use, and it works well for youtube, vimeo and all other video sources.
