@leocg That's not a valid answer. Your original answer doesn't address the specific question.

The URL for the active page looks absolutely like a Russian bot page "ffucker.ru" seriously? The extension doesn't work. "No video" but I'm literally playing the FB video. Removed this extension hopefully before my browser is infected. Opera should kill this extension ASAP

@leocg thanks. I started messing with themes. Some of them turn on background music after I turned them off. I wound up just picking a theme without music. Appreciate the help.

The background music is driving me crazy. How do I turn it off?
