Ok this is a serious question?

There is a social plug-in feature called "Facebook Connect". Facebook is able to set up a cookie on any site that has a "Like" or "share" button, giving Facebook access to a startling amount of user information. Technically, the purpose of these plug-ins is to authenticate users, but it still has the ability to collect personal information such as the IP address of your computer, browsing data, outside login information, phone numbers, etc. My question is...How do I know if I have the plug-in "Facebook Connect"? (because I don't remember signing up for that). Thanks!
