Very Good , Very Reliable

Huge fucking watermark on every video, and begs you for 28$ to remove it. This extension is spam.

I've found this add-on to be super helpful, very easy to use and extremely reliable. I wouldn't be without it. I use it very often outside of youtube to do download study materials. Highly recommended

This add-on is UTTERLY USELESS UNTIL YOU PAY THEM. It puts a HUGE WATERMARK on the video in every video created by the 'UNLICENSED' version. If it would put a transparent unobtrusive watermark throughout the entire video or they put a smaller unobtrusive watermark, I would have no problem. But they put such a huge watermark that the video is become useless to watch. I today download a tutorial video from YouTube but this video downloader made it TOTALLY USELESS. If they mention this in the 'About this extension' section in this page, I might not add it in my browser but I would not report and write this review either. I don't know if this extension / developer violated Mozilla's Terms & Conditions but if I would in their review team, I would certainly remove it from the 'Extensions' page. In an era of 'FREE SOFTWARE' movement, THIS ADD-ON IS A BLACK SPOT ON THAT MOVEMENT AND ALSO ON MOZILLA ETHICS.

非常好用，新介面更上一層樓！

I don't mind watermarks but its huge and obnoxious(I tried this on 1440p). I tried it on 720p and its still there! 720p or even 1080p resolutions and below shouldn't have it that big or at all. Also 28 usd is way too much for a product like this that may just randomly disappear. Can't recommend and uninstalling now, such as disappointment.

Video DownloadHelper ist Einfach Super Geil
