Facebook lets you experience its site through what's called "HTTPS," which is more secure version of browsing than the traditional "HTTP." If you look to your browser's address bar you'll see a website's address preceded by either an "HTTP" or an "HTTPS". The HTTP stands for Hypertext Transfer Protocol and the 'S' stands for "secure," meaning that information transfer between you and the website is encrypted and safe. Using Facebook over HTTPS is especially prudent if you access the website frequently from public Internet connections, such as via coffee shops or libraries or airports. To use Facebook over HTTPS, click the downward arrow in the top right of any Facebook page and click "Account Settings." In the "Security" tab, select "edit" next to Secure Browsing and check the box. Make sure you save your changes. With a secure connection, certain Facebook content may take longer to load; however, your information shared on the site, and your account itself, is safe from outside access.
