Safari autofill doesnt work

..Im sure this has been addressed, I have read 18 pages in this forum section, and yet cannot find anything helpful strictly to autofill. Of course, eyes will roll...here is my problem. When using Facebook, my autofill doesnt work, but it did before I updated my Safari. I know security issues etc, and maybe its a good thing but I never had my password saved, and autofill never put my password in, I did that manually. I also found many discussions about the upgrade Safari5 and many people complaining about the autofill problems. Everything is checked, except "user names and passwords". Is there any option to just save user names and not passwords anymore?
thank you very much < newbi poster >
