An address bar (also location bar or URL bar) is a feature in a web browser that shows the current URL and accepts a typed URL that the user wishes to go to. Most address bars offer a list of suggestions while the address is being typed in. Auto-completion bases its search on the browser history. Some browsers have keyboard shortcuts to auto-complete an address, and these are generally configured by the user on a case-by-case basis. Address bars have been a feature of web browsers since NCSA Mosaic.
For websites using a favicon (a small icon that represents the website), a small icon will generally be present in the address bar, or somewhere nearby to it. Favicons are specific to websites thus a generic icon will be displayed if not specified.  The address bar is also used in some browsers to indicate the security status of the web page. Various colors and padlock icons show if the page is encrypted and how trustworthy the communication is.
Some browsers address bars can be used to detect web feeds that can be used to subscribe to pages. The detection of a feed is normally indicated by the RSS icon "". A variety of other icons may also be present in the address bar if included with a browser extension.
Often times, web browsers include a feature called Smart Bookmarks. In this feature, the user sets a command that allows for a function (such as searching, editing, or posting) of a website to be expedited. Then, a keyword or term associated with the command is typed into the address bar followed by entering the term afterwards or selecting the command from a list.
Quick searches can also be performed in some browsers by entering a shortcut and search terms in lieu of a URL. For example, by associating the shortcut "w" with Wikipedia, "w cake" can be entered into the address bar to navigate directly to the Wikipedia article for cake. This feature is available in Firefox, Opera and Chrome.
Browser-specific features 
In Google Chrome, the address bar (or "Omnibox") doubles as a search plugin bar which pulls incremental returns for typed phrases from Google Suggest's pre-emptive search. An add-on is also available for Firefox that duplicates this functionality, and newer versions have the capability built-in.. This "Omnibox" is also capable of, in addition to the quick search function listed above, interpreting any non-URL phrase typed into it as a search on the user's search engine of choice.
