The Droid 2’s browser doesn’t confine you to a single window—you can use multiple ones, and easily switch among them. In fact, you may have multiple windows open without even knowing it.
Press the Menu key, and from the screen that appears, tap Windows. You see a list of all the browser windows you have open. Tap any you want to switch to. To close a window, tap the 
button next to it’s name. To open a new window, press the 
button.
