Facebook – How to get Facebook to use “http://” instead of “https://”

Facebook uses OAuth, while Google, Yahoo, AOL, and MySpace use OpenID.

For sites that only accept OpenID, you won't be able to use Facebook. Many sites accept both OpenID as well as Facebook, Twitter, LinkedIn, Windows LiveID, etc., that are other non-OpenID solutions.

If you're looking to add support for all these ID systems on your website, you might want to check out Janrain's Engage.

Check (and keep checking) the privacy settings on your account.

There's a "Public search" option - make sure that's set to disallow.

There's a option for "Information accessible through your friends" make sure that you clear all the check boxes on that dialog.

There's an "Instant personalisation" page - not available for all users as yet - but when it does become available make sure you clear that option too.

There are options for Facebook ads to use your data - clear both options.

You have to keep checking because Facebook regularly change the options and the defaults are to be more open than you would like.
