I have added the AddThis code to a client site, and its not working in either Firefox or Safari. In Firefox, using the Error Console, I got this:
Timestamp: 7/24/12 4:52:20 PM
Error: window.open is not a function
Source File: http://s7.addthis.com/static/r07/core025.js
It looks like an error with an AddThis script - is there an update I missed?
