This is the extension that drops a red button in the Youtube page right below the video. Clicking the button doesn't provide any format or resolution options - only one to download an MP4 file. OK, fine, I'll take that. Things look promising when a dialog box opens with the actual name of the video (i.e., not some cryptic, random filename) to select target directory. After selecting the target download directory the download appears to start and goes for a few bytes but fails. It looked so promising...

I'm guessing the few positive reviews are friends and family because it doesn't seem to have worked in years!?

I've tried multiple times to download a video with this add, but it never works. So I'm using udl helper and everything works fine

Hot garbage. I don't understand why Mozilla lets useless junk like this get uploaded here.

A Download button opened
http://webrikk.com/index.php?url=https://www.youtube.com/watch?v=VoS1utjM6WU
and the site is unreachable. That's all it does.

Doesn't work. No button appears after adding it to firefox.

ok

The download button is present only in desktop mode, and all it does is sending me to ww12.webrikk.com

It's very good
