Need pay to download, lol, really? :D

I'm not downloading anything that tracks my entire browsing history, as well as login information.

Youtubeの仕様変更により、このアドオンは現在利用できません

Used to work well but is now totally inoperative. Website does not inspire any confidence that the extension will be fixed.

Paywall to download mp3 (But works fine if you want to dl video)

Very Good, Thank you.

Doesn’t work

Asking for paid Pro version for fullHD. Others do it for free.

Pretty nifty addon to generate nothing but errors that say the addon no longer supports downloads

only for money, nothing free inside

Didn't work at all; just sat there generating something or other.

no longer works :(
