Works perfectly! Thank you!

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.

This extension reads All your surf history on All sites! And probably send it back for ads and sells it to third parties companys! Stay Away !

Does not work in Linux Mint 20.04
