The test over at <a href="http:&#x2F;&#x2F;ip-check.info" rel="nofollow">http:&#x2F;&#x2F;ip-check.info</a>, by JonDo, is more comprehensive at the expense of not using information theoretical measures like those of Panopticlick, which would give a realistic (if biased) view of browser fingerprint uniqueness. They’ve developed a Firefox setup profile called JonDoBrowser that’s optimized for their own test. While the HTTP headers JonDoBrowser sends to sites can be easily distinguished from those of other browsers (though they’ve attempted to standardize HTTP headers within their own ecosystem), their proxying service compensates for that by withholding all traceable details and eliminating all forms of local storage, thus providing better privacy.<p>They’re located in Germany—a big legal plus—and their service uses an international chain of independent servers, but they charge for data rates greater than a few hundred kilobits per second. Thankfully, the browser profile also supports faster Tor proxying while maintaining the same degree of personal privacy. It also supports anything you can configure from your computer’s settings, but if that means something other than Tor or JonDo, it’s probably not redundant (i.e., comprising multiple independent proxy servers) and therefore less reliable. It can be downloaded from <a href="https:&#x2F;&#x2F;anonymous-proxy-servers.net&#x2F;en&#x2F;software.html;" rel="nofollow">https:&#x2F;&#x2F;anonymous-proxy-servers.net&#x2F;en&#x2F;software.html;</a> for those who wish to try it, I’ve found it works best with Firefox ESR, which can be downloaded from <a href="https:&#x2F;&#x2F;www.mozilla.org&#x2F;en-US&#x2F;firefox&#x2F;organizations&#x2F;all" rel="nofollow">https:&#x2F;&#x2F;www.mozilla.org&#x2F;en-US&#x2F;firefox&#x2F;organizations&#x2F;all</a>.
