Dear, Since two days, my firefow desktop browser (windows 11 - surface pro) switches to tablet mode (larger address bar suggestions etc) when the computer should be in desktop mode. Situation: - Surface tablet without type cover connected - docking sation usb -c - 2 external displays connected - bluetooth keyboard and mouse connected Windows recognizes 'desktop mode' since all menus (taskbar e.g.) are behaving in desktop mode (not larger). However, Firefox for some reason switches to tablet mode (see image attached). When I connect the typecover keyboard, firefox switches to desktop mode. So it seems as if FF thinks the PC should be in tablet mode because the typecover is not connected. But it shouldn't because a dock is connected. It worked perfectly for years, but since two days not anymore. It is not a major issue, but rather inconvenient. I already restarted PC and reinstalled FF. kind regards Jan
