Bad Firefox :-(
Use Lynx! :-)
But on a more serious note, this was warned of many months ago by security
researchers. Unfortunately people don't understand just how prevalent online
tracking is and how sophisticated it has become. I think even the people who
make up the standard probably aren't aware of how seemingly-harmless
functions can be used maliciously. I think at this point we should just
assume that any function that is able to provide a pseudo-unique method of
identification will be used in this way. I don't think this is unique to
Firefox at any rate.
