I use chrome too, and I hate this feature because it makes navigation *slow*
The top one is Chromes "Windows 8 Mode"(full screen tablet mode) the bottom is "Windows desktop Mode", just go to the hamburger icon and change modes.
Hello, it is the wrench icon located at the top right just below the close button.
looks like the new chrome bookmarks feature
look for Enable Enhanced Bookmarks
Change this to be disabled
