When you click on a Spotify link wherever it may be, it brings you to the Spotify website, and from there you have to click 4-5 separate times to get the link to open in the desktop app. This extension converts the Spotify URL to the Spotify URI and opens in Spotify automatically. The first time you run the extension, it will ask you where you want to open it, if you select "Spotify" and tell it not to ask you again, Spotify will open automatically when a link is clicked.
