The good people of JonDo / JAP have created an anonymity test:
https://www.jondos.de/en/anontest
Proxy settings, disabling Java and Javascript, and disabling cookies can all easily be done from within the graphical Configure Konqueror. Language is already set to en. By editing kio_httprc, I can disable referrers and set a global fake user agent with the following lines:
SendReferrer=false
UserAgent=Mozilla/5.0 Gecko/20070713 Firefox/2.0.0.0
So far as headers go, according to the anonymity test, that gives me three that show up as good, one medium, and three bad.
What's still needed:
* Referrer should be forged to the current domain, not just blank. (So, when browsing this forum, the referrer should claim to be
http://www.kde-forum.org/ regardless of the actual referrer.)
* HTTP_ACCEPT_CHARSET, HTTP_ACCEPT, and HTTP_ACCEPT_ENCODING all need to be customised. I tried adding Charsets=utf-8,* to kio_httprc, but that just prepended utf-8,* to the default list.
Help?
