If any extension opens up a new tab without my intension, even worse - while I'm working or watching a fullscreen video, I usually give it a one star rating and delete it forever. Because opening tabs is a huge disrespect towards users.

GOOD VIDEO DOWNLOADER.

Well.... in short: On my Ubuntu machine (Ubuntu 22.04, Firefox 107.0.1 64bit) I get mostly errors on YouTube. Interestingly one download yesterday worked fine - but it was the only one.
The downloadable files are listed, but... as mentioned: VideoDownload Helper says: Data may be corrupt - and refuses download. Only those videos are downloadable, which - anyway - can be downloaded using "download media" from Firefox directly. And this isn't the sense of the addon, because such downloads are simple to manage without addon.
Edit:
This is strange:

This WARNING irritates me - any idea?

GOOD VIDEO DOWN-LOADER. 4.4 stars. IT would not automatic upgrade to 1080P or to 4K video. only original format available to downloads. also it slow to downloads. SLOW SPEED HAS IMPROVE. STILL NEEDS WORK to capture video faster.
download slow, no upgrade to 1080p yet.

PLEASE AUTO UPGRADE TO 1080P or 4k.
This app only downloads original formal quality.
IT NEEDS TO AUTO UPGRADE TO 1080p or higher.

its very easy to use

Super útil para descargar videos online

Absolutely brilliant. Extremely simple and functional. Well done!

Very to the point. If you can get the companion program to be recognized by the application, it's the most seamless and no-BS of the video downloaders.

非常に優秀なソフトです。
