Using the Chrome web browser, close browser tabs on an Android device by using the tab switcher icon. This icon may look like a square or like a pair of stacked rectangles.
To close a single tab, click the tab switcher icon and either touch the X in the top right corner of the screen, or swipe left. To close all tabs simultaneously, click the tab switcher icon and open the Chrome menu, which looks like three dots stacked vertically. Next, touch Close All Tabs. To open new tabs, choose the Chrome menu and touch New Tab. Swiping over the tab switcher icon allows you to view all open tabs.
