in case of F11 (fullscreen) the navigation-toolbar looks really VERY strange... (theme: orbit retro 1.2, +multizilla)
-> invalid (third-party Theme problem) Please reopen if you see a strange navigation bar with classic or modern. (and attach a screenshot)
Reporter, we don't support the orbit theme. Verified invalid.
