I can't disable full screen mode in opera without a special button.
Previously, I was able to freely exit full screen mode without using the button in the upper right corner. I used this strip to the right of the tabs (it's comfortable). Now it disappears when I open many tabs at the same time. It's still half the trouble. When I exit full screen mode, this bar does not appear and I cannot move the Opera window around the desktop at all.
Tell me how to restore this strip
