This is very useful to me.

The extension leaves a watermark on all the videos unless you pay.

eccellente

esta extencion es genial gracias

Prático, rápido e eficiente. Cumpre o que faz de forma excelente. Depois que conheci, nunca mais passei trabalho para baixar vídeos dos principais canais de conteúdo da internet.

Awesome

Excellent. Fast and reliable. Sometimes nevertheless it cannot find the video stream ! SOmme times it starts then stops unexpectedly and never completes ! I have no clue on why.

Requires additional 3rd-party software to be installed. Nope!

pretty useful, help me a lot when I got some videos to download!

I wouldn't recommend using this. This will put a watermark on the majority of your downloaded videos unless you purchase a license. The biggest alarm is that this add-on requires you to download an external program (which it doesn't state anywhere in the description). The site claims that it's necessary and provides the source code via github, but no hash to verify it with the source code. Soon after downloading this, I started having some odd behavior with a service via svchost.exe causing high memory spikes, which I had never had since I've installed my OS years ago, and this was the only software I've installed recently in months.

I'm still checking whether the .exe of this addon was the cause, but I would be extremely careful and compile the companion app from the source code yourself if you're set on using this. There's another safer download tool called youtube-dl that is open source, well documented, and free. It's command line only but there's a gui front-end for it that also has instructions to compile directly from the source code.

good extension often update to meet the changes

Consistent performance, much appreciated!

It was very usefull for me for taking big video files with time-limited acess.

Download works in most cases but conversion (if needed) is very, very slow.

works when most others do not. Captures BOTH streaming and full file downloads. Have to search around if stream is encrypted to find a host that allows this extension to fully capture it.
