This guide explains how to make sure that you’re using the secure version of Facebook (https) instead of the non-secure (http) version.
1. Log into your Facebook account and click on the Account dropdown menu on the upper right side of the page then click Account Settings.
2. On the My Account Settings page click on Change next to Account Security which is third up from the bottom.
3. Then you should see Secure Browsing (https). Check the box next to Browse Facebook on a secure connection (https) whenever possible…and then make sure to click Save. If you don’t see the option yet, be patient and keep checking back daily, as they’re slowly rolling out the feature to all users.
4. Now when you login to your Facebook account you should see “https://” before the URL in the address bar.
That’s it. Now when you’re on your Profile and Home page you’ll have a extra peace of mind knowing it’s secure. However, keep in mind that some pages may load slower, and it may not be available on all of the pages you access in Facebook, but at least they’re trying.
Also, if you don’t see the option yet, you should be able to add “https” in the address bar manually to get the encryption feature until the Account Setting is available to you.
