At work , i am behind a ISA firewall. Social Website like facebook, youtube etc are blocked by the network administrator. These days almost all the website have a link to facebook for share. therefore, when i visit any website, just because these links are blocked, the browser asks for Proxy Authentication.
This gets very irritating espacially when i have to click cancel button for atleast 4 times on a website and sometimes even more than that.
Is there any browser Add-on that can just hide these pop-ups? This behaviour is happening in almost all the browsers Chrome, IE, firefox etc.
