Tap the Share button on the browser’s toolbar — that’s the rectangle with an arrow pointing upward. It’s on the bar at the top of the screen on an iPad, and on the bar at the bottom of the screen on an iPhone. Tap the “Add to Home Screen” icon in the Share menu. You’ll be prompted to name the shortcut before tapping the Add button.
Chrome: Tap the menu button and tap “Add to homescreen.” You’ll be able to enter a name for the shortcut and then Chrome will add it to your home screen.
Firefox: Tap the menu button, tap the Page option, and tap Add to Home Screen.
