Test Your Browser

Browser Fingerprint

Is your browser configuration unique?

Your Browser sends information that makes you unique amongst millions of users and therefore easy to identify.

When you visit a web page, your browser voluntarily sends information about its configuration, such as available fonts, browser type, and add-ons. If this combination of information is unique, it may be possible to identify and track you without using cookies. EFF created a Tool called Panopticlick to test your browser to see how unique it is.

You need to find what most browsers are reporting, and then use those variables to bring your browser in the same population. This means having the same fonts, plugins, and extensions installed as the large installed base. You should have a spoofed user agent string to match what the large userbase has. You need to have the same settings enabled and disabled, such as DNT and WebGL. You need your browser to look as common as everyone else. Disabling JavaScript, using Linux, or even the TBB, will make your browser stick out from the masses.

Modern web browsers have not been architected to assure personal web privacy. Rather than worrying about being fingerprinted, it seems more practical to use free software plugins like Privacy Badger and uBlock Origin. They not only respect your freedom, but your privacy also. You can get much further with these than trying to manipulate your browser's fingerprint.

WebRTC IP Leak

Is your IP address leaking?

WebRTC is a new communication protocol that relies on JavaScript that can leak your actual IP address from behind your VPN.

While software like NoScript prevents this, it's probably a good idea to block this protocol directly as well, just to be safe.
