VOCE NAO BAIXA O VIDEO, PEDE ASSINATURA PRO.

Don't claim to be a free add-on when the add on doesn't work unless you "donate" to it.

good

I just downloaded and installed this addon. On YouTube button appears. When I clicked on it, a message appeared - "Downloading as 1080 is not possible." In this message, there is a link to such rules on YouTube.
In short, this is a useless addon.

Я только что скачал и установил этот аддон. На Ютуб появляется кнопка. Когда я нажал на нее, появилось сообщение - "Скачивание в качестве 1080 не возможно". В этом сообщении, идет ссылка на такие правила на Ютуб.
Короче, это бесполезный аддон.

Only Pro users can do anything. Don't use this if you don't intend on paying.

Não salva em mp3, em nenhuma forma precisa ser PRO. Não baixem. Deveria pelo menso uma opção free

not free. they want you to buy the pro version to get full functionality of it.

Спустя два года по-прежнему не работает. Говнище.
