Autofill settings

My autofill used to work nicely.. It had all my info so I didnt have to constantly type in my info on web pages over and over..... No that is not the case. It seems to only know my Face book info... Which is nothing.. just my name. And this weird addresss that goes a little something like @887730098facebook.com

Anyone know how to fix this so it goes back to my correct info and not any facebook info?
