The standard Android browser (at left) uses a simple visual approach to displaying bookmarks. Chrome is much more complicated, as shown in the three screens at right. First, there are three bookmark folders: desktop, mobile, and other. When you open any of those folders, you get thumbnail icons for each page rather than a preview thumbnail. You can still get those thumbnails if you tap the grid icon button at the bottom of the screen.
To save a bookmark in Chrome, tap the star icon button in the menu; it replaces the Add Bookmark menu item in the standard browser. Also, Chrome has no history window for pages visited, unlike the standard Android browser.
