How anonymous are you when browsing online? If you're not sure, head to StayInvisible, where you'll get an immediate online privacy test revealing what identifiable information is being collected in your browser.
The site displays the location (via IP address) and language collected, possible tracking cookies and other browser features that could create a unique fingerprint of your browser and session.
If you'd prefer your browsing to be private and anonymous, we have lots of guides for that. Although StayInvisible no longer has the list of proxy tools we mentioned previously, the site is also still useful if you want to test your proxy or VPN server's effectiveness.
