Don't make me laugh. You seriously think after buying an ad firm that "privacy preserving attribution" is not a euphemism? And I'm not the only one that sees it that way:

• heise
• lifehacker
• privacyguides

Why don't you stop being to blue-eyed? Mozilla isn't the privacy preserving browser. Hasn't for a long time. Its major reason for existence is to be a functional "alternative" to Chrome that isn't built on top of it.
