I am using the old YouTube and the button will not show.

doesn't work - there's a button on the YouTube page but it just says it's disabled and to add the add-on.

It was working for a few days, now not.

Doesn't work. Only add-on, no download button.

Çalışmıyor. Eklentiyi kaldırıp tekrar kurdum, fakat değişen bir şey yok. Video altında simge çıkması gerekli. Simge yok.

Te pide instalar más cosas, para enviarte a una página comercial externa. No aparece ningún botón de descarga.

No download button... useless add-on.

The website works fine when you cut & paste a URL to it. However there is no "Download as" button below the video on the Youtube site as it says in the description. This is on Firefox 57.
