Along the right edge is the "quick-access bar," a stack of thumbnail views of your popular pages selected on the basis of how recently and frequently you visited them. In the upper left are buttons that take various actions. For example, if you've selected some text on a Web page before opening the new tab, that text will be presented as a search that can be performed by clicking the button in the new tab.
