There are videos on YouTube that I can't download. Why?
YouTube Video Downloader didn't receive the needed data which means that the video is currently unavailable. This is a temporary problem. Please wait for some time and try to download it again. If the problem persists, then probably the problem lies in country or copyright restrictions.
Is this service free?
Yes, it's completely free.
Firefox browser is unable to download the video?
Probably when you clicked the Download button, you have been redirected to the page where the video started playing. In this case there are two ways to download a video: 1. You can click the right mouse button to save the video. 2. You can use another browser (e.g. Chrome) instead.
