I am using spotify just from today on a Linux box (Ubuntu 16.04.3) with firefox 59.0.2, and I start the play of an album, and then the first or second song just stops. Clicking on "Pause" and then "Play" does not help - the button stays in state "Play".
Do I have to reaload the webpage every 2 minutes or so to make it work? Or is spotify not suited to listen to music? Or is this a joke?
