Technically, it's still a good old Video Download Helper but now it's trying to install a 3rd party app in your OS for the features old one had out of the box. It's a downgrade.

Eventually it will demand money from you

よいことはしっかりDL出来ることだ
悪いことは「俺様とライセンス契約しないと録画内容に大きなモザイクマークをずっと貼り付けるぜ！」とライセンス契約を強要することだな

This works yet it puts a huge QR code in the corner of the screen. A small one OK but really a 3x3 inch square on a 17 inch monitor.

The addon seems to be good, but: I left my laptop to download few long videos and then i came back - the battery was almost empty.

Instead of direct downloading, there was a transcode of video in background.

ugly QR code watermark taking up one-sixth of the screen

This was a wonderful app while it lasted. Unfortunately, they eventually tried to make me pay for the service. Also it was supposed to be a lifetime payment but from my own research I've learned people are being asked to "upgrade" after as little as six months.

Used to be amazing, but recent updates have caused most downloads to fail and have to be restarted multiple times.

Improved; getting better, considering that it's handicapped by trying to function in microsoft's cluster f*ck abortion known as windows 10 (or any version of windows after 7, for that matter); it's still improving. However, I wish that it would add titles when downloading TV series episodes. I still occasionally find some videos that can't be downloaded, especially from Tubi, which has gotten worse in the last couple of days. And actually nothing from PlutoTV will download at all.

the older versions were better...

Stopped working with update?

Requires additional executables, which are not available for all platforms.

不值得使用，下載後的影片，會出現超大的二維碼廣告！

i thought it was free. turn out to be a 28$ extension. not worth it

works but puts a big qr code on the video unless I pay them 20€

Used to be a good add-on now everything has a watermark on it.

Fue de las mejores para descargar videos; con las actualizaciones nuevas, se inserta un código QR en los videos descargados, que desmotiva volver a usarla

Old version is lots better.
It can downloads any videos. This one said Dwnload failed.

Since the change of the logo and with the update to it, it only downloads 10% of the videos at a time.

Loved this app until the developer slipped default action to open in the side panel in the manifest.json file.

Wrong thumbnails, detects a billion other streams while only one is playing.

Перестал загружать.

The developers of this app should explain to us what purpose they need to force us to provide the following permissions:
Read and edit your browser download history
Access the tabs
Access activities while browsing
Access data from all websites
Access and edit your bookmarks.
In the latest update it automatically installs in the sidebar, overlapping the bookmarks while before it was on the toolbar and there is no way to move it.
Finally, it has become very slow to download compared to the past, and therefore I think I will reluctantly remove it.
