This is the worlds best extension, if like me you are constantly learning and wanting to stay ahead of your game. It allows you to watch virtually any video on the internet at a faster speed, saving you heaps of time. I often watch TED talks at twice the normal speed, or new material by key mentors. I have even listened to a video at 3 times the normal speed and I could actually understand it.
