It works somewhat, but it heavily throttles download speed to below 100kbps. Unless you pay for the 1080 download (which I usually don't need for what I need to save) and then it goes to over 2mbps. This is the same practice as any other paying download site. Add to that the quality is horrible. The 720p looks like 360 and nothing like the youtube video. So it certainly doesn't access the youtube stream directly as they pretend. Last, some 720 options show smaller size as 360. Totally impossible. This is rubbish!
v 18.4 is already submitted and pending review by Mozilla. Pls. update your review as this is something we do not have control over. Is is sad to see people not leaving a positive review when it works and leave a -ve the moment it doesn't :(
