If you see the message “Playback of protected content is not enabled” when you try to use the Spotify Web Player on Chrome or Firefox, simply enable the Widevine plugin with these steps:

FOR CHROME

• Enter the following into your browser address bar: chrome://settings/content.

事实上，360的设置里面根本没有这一项，也就是说，我用不了spotify。


之前一直用安全浏览器 7.1，一点问题都没有。这次用360 安全浏览器 9.1，spotify用不了。

在地址栏输入se://extensions后回车，用开发者模式试试
