Anyone else having trouble using Google Play Music in Firefox? When I select a track it never starts playing. It works just fine in IE and Chrome. I'm using v 25.0 on Windows 7 I have tried the steps described here: https://support.google.com/googleplay/answer/1196374, without success. Every plugin is up to date. I've also tried running in Firefox safemode with all extensions disabled, but the problem persists. Any help would be appriciated!
