This extension has been an open-source project from day 1 with an MIT License. On the 28th of January, I made my first commit on Github. At the time, I was living in Tokyo and I used to listen to music on Youtube™ while working. I needed an easy way to control the music playback from any web page even if the browser is in the background. At the same time, I wanted to learn how browser extensions are created, and that's how the Youtube™ Controller Extension was born.
