How do I delete a specific cookie by name in Safari?
You can still see individual cookies using Safari in developer mode.  Go to "Safari-->Preferences-->Advanced" and enable "Show Develop menu in menu bar".  Navigate to the webpage that holds the cookie you are looking to remove.  Go to Develop in the menu bar and "Show web inspector".  On the left hand side there will be a folder "Cookies" that holds the data from that site.  You can right click them and delete certain ones.
