I tried "Video DownloadHelper" and this add-on completely blows it out of the water. I really appreciate all the hard work that has gone to it by the developer who has been doing this as a hobby. Man, props to this guy! I went ahead and donated because I would hate for the application to stop working due to lack of funding. It's so EASY to download videos and audio without having to leave the page and go to third party sites full of malware and ads. Made an account just so I could leave this review.
