So, I came across this site run by the EFF that tells you how unique your browser configuration is, which in turn tells you how much information is shared with the sites you visit. Apparently mine is “unique.”
“Is your browser configuration rare or unique? If so, web sites may be able to track you, even if you limit or disable cookies.
Panopticlick tests your browser to see how unique it is based on the information it will share with sites it visits. Click below and you will be given a uniqueness score, letting you see how easily identifiable you might be as you surf the web.”
