"“It is widely known that cookies can be used to track users. However,
even privacy-aware users are trackable by the properties the browser
sends with every request. Based on information like the browser
vendor, plugin versions and the installed fonts, a fingerprint may be
created that uniquely identies a browser.”"

"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.
Only anonymous data will be collected by this site."

I just tried it. Results: "Your browser fingerprint appears to be
unique among the 2,086,438 tested so far. Currently, we estimate that
your browser has a fingerprint that conveys at least 20.99 bits of
identifying information."
