You should see the more autofill choices in "Forms and Autofill" just below "Logins and Passwords" when form auto-fill is enabled (available).

there is no logins and passwords section. how do i enable form auto-fill? I do not even see an option to turn this on.

You can look at some "extensions.formautofill" prefs on the about:config page and set this pref to "on" (without quotes).

• extensions.formautofill.available = "on"

You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.

ok, i did that. but, I still am unable to see any settings to save autofill for addresses?

Did you click the blue OK button to confirm the change ?

Yes I did, that’s why it is greyed out now after I clicked the blue to save it.
