Strange hill to die on. This change which balks at the face of its users seems representative to me that those who operate this browser have decided not to make this browser function for its users, but for themselves.
I'm not sure what the catalyst was that changed Opera from being a user friendly browser to something that actively suppresses feedback.
Personally, I'm going to try Vivaldi. It seems that not only does it have this feature, but some other features I've been thinking about. It's frustrating as I thought this was going to be a browser I could use for a long time, but I guess it just didn't pan out that way.
