I just downloaded it today from the Opera site and none of the features or menus you describe are present.
Same here, I still don’t see anything anyone is telling me is there.
Mine’s been fully-customized since 2009; I’m trying to help you from memory of what it looks like as a new app.
Try right-click 3/4-1” down from top, more or less, to get “customize > appearance”.
Let me try to d/load a new copy and I’ll be right back...
How does anybody know Opera isn’t a gaystapo sympathizer?
Google (Chrome) is. Apple (Safari) is. Microsoft (IE) is.
Just switched to palemoon.
