What extensions do you have installed? There's a known and unfixable issue with browsers that both block JS and absolutely block all requests to tracking domains (eg AdAway, which modifies /etc/hosts).

To incentivise better behaviour by web publishers and advertisers!
It's kind of weird for something specifically dedicated to measuring tracking to get so confused by an anti-tracking mechanism.

Maybe if it could have some legal teeth to it, otherwise it's too easy to lie to get your tracker unblocked.
I switched off "Do Not Track" in my options since only good-behaving websites listen to it, such as those using Piwik analytics, which respects privacy. Therefore I only would harm good people with Do Not Track on.
