using firefox with anonymous proxy. some sites can see still real ip. I have been researching this and found out there is something called a flash cookie or something like that which reveals your real ip. is there any firefox addons that will block these? I am using noscript addon but that didnt block it. how can i run tests to see what other websites can see about my computer? I remember someone here (maybe FBguru) posted a link a while ago which would show you everything that a website could possibly see about your computer, including your ip, your operating system, and the time on your computer. does anyone know what that website was?
