it was working great so far, but today no button is there any more

Ne propose pas d'enregistrer en 1080 :/

You have to pay to download anything more than poor quality.

May I ask why you need to access our data for all websites since it's only supposed to work on Youtube?

Видео 1080 и больше - платно для скачивания. Лучше купить подписку на Youtube.
