Facebook has finally added the ability to access the site via a HTTP Secure (HTTPS) connection, which should drastically increase security for users.
HTTPS provides a combination of the HTTP and SSL protocols, enabling encrypted communication between your computer and a web server. Without it you’re exposed to sniffing attacks on the network; for example, if you’re using a public Wi-Fi to access Facebook via plain HTTP, someone using the Firesheep add-on for Firefox can easily retrieve your data. HTTPS makes it far more harder to do that.
The feature is available as an option on the Account Settings page. If you don’t see it yet, don’t worry: Facebook will be gradually rolling it out over the next couple of weeks.
