An address bar, or location bar, is a widget in a web browser which indicates the address (URL) of the web page currently viewed. A new page can be viewed by typing its address to the address bar.

In most browsers, the URL value can often be auto-completed, either by looking up similar URLs from the history or by using keyboard shortcut for address completion. For websites which use favicon (a small icon that represents the website), there will also be a small icon in the address bar.
