The autocomplete feature is a very useful and efficient tool to use when browsing the web. As you type in the first few letters of a web address, Firefox will suggest one web address that matches. You can type in additional letters until you see the web address you want and press Enterto go there. In this tutorial we’ll show you how to set Firefox to fill in automatically while you’re typing a web address.

• Open Mozilla Firefox Internet Browser.
• In the Location bar, type about:config and press Enter. This will redirect you to a warning page that says This might void your warranty!
• Click the button that says I’ll be careful, I promise! to continue to the about:config page.
• Type the preference name, browser.urlbar.autoFill in the Search field located at the top of the page.
• Change the value of this preference to true. To do this, simply double-click where you see the preference name browser.urlbar.autoFill. To turn off, double-click the preference name to change its value to false.
• Close the browser.
• Reopen Firefox and type in a web address to try out. Once you see the address you’re looking for, stop typing and press Enter. This saves time and works great!
