This is by far the easiest down-loader for videos I have ever used. It downloads at a very fast speed and I am able to download up to 8 videos simultaneously, plus you covert the them into a number of different formats. I just love to click the video and quickly move on to next one, and the next, and the next, etc. I've donated and I will continue to donate to the smoothest down-loader for videos < I have ever used. Thank you, Firefox and Mozilla
