MadAzrae84 is right its a scam. after you pasted the video URL then chose the video quality then click download from server1 2 3 or 4 it automatically takes you to opera.com/computer/thanks? witch downloads the opera gx setup automatically or it takes you to a bunch of sport betting sites and a few verify that your not a robot sites one click download maybe for opera gx what a joke it doesn't work should be removed from the addons page
Tiene que copiar la URL y pegarla en una barra dentro de la extenxion, que te lleva a una pagina externa llena de publicidad lo maximo que descarga es 1080, no descarga ni 2K ni 4K
