DAUCLAIR  That's a really strange issue, sorry you are having trouble. I've tried replicating it but I'm unable to do so. I had another friend log into Facebook in Safari and used the Remember Me checkbox to save a cookie. I then closed Safari and ran AddressBookSync. My friend email started in the username field (this is to be expected) because the Facebook cookie was saved, but when I cleared it and put in my login info it showed my username in the title bar and my friend list.

I'm using the MkAbeFook framework for OS X to handle all of the Facebook login detals and API calls (http://pointlesscrap.net/mkabefook/). I'm trying to looking into any known issues with Safari cookies using this framework, but I haven't found anything yet.

Just as a test have you tried choosing Reset Safari... under the Safari menu to clear the cache/cookies and then run AddressBookSync and logged in?

Anyone else having similar issues with Facebook cookies in Safari?

DAUCLAIR  Are you logged in as the user into the mac or is it your daughter's account? The program only syncs to the address book of the person currently logged in. Firefox vs. Safari should have nothing to do with it, whatever Facebook email/password you log in with will sync with the mac Address Book of whoever is logged in.

DAUCLAIR  Just put out a 1.1.1 update which fixes the bug which caused the program to crash on startup for users of 10.4. I'm sorry that got overlooked, I will be sure to test on Tiger before new releases from now on.

DAUCLAIR  Thanks for all the feedback so far, keep it coming! I want to make future versions of AddressBookSync as useful and as good of a user experience as possible. Thanks for trying the app!

DAUCLAIR  If you are asking about syncing phone numbers and emails, there is not a good chance of the app ever doing that. The Facebook Development Platform Terms of Service prohibit accessing these through the API. Right now profile pictures and birthdays seem like the only logical thing that would be useful to sync between Facebook and Address Book.

DAUCLAIR  I only put down Intel down because I don't have a PPC Mac to test it myself with. I believe it should work fine on either Intel or PPC as long as its 10.4+, would be interested for any feedback if you try it.
