Firefox disables Google Analytics even without any add-ons if you have the anti-tracking options on. This also works on "special" pages. Go to addons.mozilla.org and have a gander at dev tools: [GA] Do Not Track Enabled; Google Analytics not loaded and tracking disabled Edit: actually, this is them simply respecting your DNT policy, but Firefox also has a special blocker for these things. It also ships with some shims that unbreak badly developed sites which break without Analytics scripts present.
