I've always allowed Safari to autofill my passwords for sites like Facebook, Amazon...you name it. Now it suddenly won't work. All the check boxes in my autofill preferences still seem to be there, and all the accounts that I allow it to autofill are still listed. However when I try to log into a site, the password box is empty, and then when I do type it in manually, Safari says that the password is different to the one it remembered (it's not) ... and offers to remember the new one. If I log out and try again, the same thing happens. Weird and VERY annoying. Anybody else had this? This is version 5.1.3 btw.
