In October, we covered how Firesheep, a simple Firefox add-on that took advantage of a flaw in HTTP connections, could give users full -- but illegal -- access to the accounts of other Internet surfers on open Wi-Fi networks, including Twitter, flickr and Facebook.

Facebook is adding full HTTPS support for its site, to protect users from attacks like Firesheep that found holes in the old HTTP connection.

The catch, however, is you have to turn it on. Here's how:

1. Log in into your Facebook account.
2. Click on "Account" in the upper-right-hand corner.
3. At the drop-down menu, click "Account Settings."
4. On the new page, scroll down to and click "Account Security."
5. Click the "Secure Browsing (https) box.
6. Click "Save."

Should you run into problems, technology blog lifehacker.com put up a video tutorial on how to set up HTTPS browsing on Facebook.
