    "Deep in the browser’s privacy settings, Firefox introduced an experimental “privacy-preserving ad measurement” toggle, enabling it by default without explanation or disclosure."

This isn't even the first time Firefox has collaborated with an ad or marketing company, rolled out a feature behind a checkbox that users didn't know about, turned it on by default. See the case of the 'Alternate Reality Game' ad campaign for Mr Robot a few years ago: https://news.ycombinator.com/item?id=15940144

I stopped hearing when Mozilla talks about privacy or caring about users. Most companies that treat their users like Mozilla just do it, but it actually adds insult to injury that Mozilla tells you they care, tells you you're important while they do the same things. It's gaslighting or manipulation or lying or something but I'm not going to listen to them any more.
