Do Not Track and Mozilla.org

Posted on July 31, 2013

There is an interesting bug report and associated discussion over on the Mozilla bugzilla which reveals several points about the Do Not Track HTTP header, the Mozilla website and Firefox’s implementation of this protocol.

I messed around with the DNT header when I first saw the setting in Firefox and I was amused to see that the Google Analytics tracking pixel was still firing. I thought this was either because they would filter the DNT requests when processing the data or because Google deliberately chose to ignore the header. I never considered that being tracked by Google in this way could actually be compliant with DNT; in some ways this is worse because it makes the protocol basically useless
