We have AutoComplete enabled on our computer. My question is, will just the email addresses entered on a certain site show up in the drop down menu, or will all email addresses entered on other sites show up on the drop down menu too? It has become an issue, and I really need to know I am not crazy. My husband thinks I have opened another facebook, because an email address showed up yesterday (that I have never used on facebook, and haven't used for anything in 2 years). I know that I only have one, but he does not believe me.
