block facebook except when on facebook
Posted: Sat Feb 26, 2011 5:53 pm
lots of websites run code loaded from facebook, and i would like to disable scripts from facebook.com/.net. however, i want to allow facebook code to run when i access facebook directly. essentially, i want to enable scripts for a website online while on that website, but not when that website is a third-party website (relative to the website i am accessing). is this possible?
