I have my firewall on the setting "Set access for specific services and applications." When any other application besides Webkit wants to access the internet, it asks me if I want to allow network connections, or disallow. On safari (not webkid nightly), it asked me once, I said allow, and then it never asked me again. With Webkit, it asks me almost everytime (almost 100% sure it's been every time) when it's opened. I looked in the firewall, it's clearly on the list of applications, along with safari, as "Allow incoming connections."
