Rated 5 out of 5 stars

Video DownloadHelper is by far the best add on that you can use. I moved to the Philippines, where the internet is a bit slower, the 3gpp option works well here for faster downloading. When youtube does changes to the system, the developer of Video DownloadHelper keeps this add on up to date. It is the best one out there. Thank you Mig
