Safari 6 does not fill username and password fields
Since my update to ML 10.8 and Safari 6.0, all my websites with stored passwords don't get their username / password fields populated.
My settings seem to be correct, with the checkbox checked in Preferences to fill the password fields automatically, and I see my usernames / passwords in the Password tab for the websites.
I also reinitialized Safari, except for clearing out the passwords (because I want to keep them, of course), but still no success
Any idea what's going on in Safari 6?
