@st333v I don't know how some of this stuff works. I do the best I can I guess. I thought the revert site was made by same author. We did figure it out. Mode 2 does work in group yes .... sorry for mis-posting or whatever.
It works! I found out that it only works without adblockers on. Try turning of your adblocker first. Then play the video on youtube and after that click on the pinned downloader. It opens maybe first an ad site, x it out (maybe several times) and a downloader window pops up.
But, there are better YouD ones out there.
