It used to be great. Now, it's totally disappeared. I've updated Firefox. I've uninstalled and re-installed this extension. It still fails to appear.

unpossible to download mp3 without subscription

Need pro subscription to convert. Money grab.

Bez PRO niczego nie pobiera.

Pro subscribtion for conversion? free options out there that works 100 times better. money greedy monkey!

can't use conversion if not a "PRO user"...
keeps selling a subscription, so thanks, no.... i would more gladly pay for a youtube subscription then get some money to the real authors of the video

charging for downloads now

Не работает заявленное скачивание в mp3

You can't download audio files because of some "youtube server" stuff, which is complete bullcrap because I don't see youtube-dl complaining

attempted to dl a mp3, informed in a long winded excuse about server infrastructure and that I need to upgrade to PRO - instead upgraded to UNINSTALL
