I guess I am just a bit more optimistic about Mozilla as a company than you might be. Sure they could abuse the study mechanism to spy on people and hack my browser. I just assume that they have neither the motivation nor the lack of ethics to do so. And I have automatic updates enabled anyway, so they can already install whatever binaries they want on my machine. The other thing is that it's not like there are many other options for me. The only mainstream browsers I could realistically use are Chrome, Firefox and Edge. Out of those I think Firefox probably cares the most about my privacy.
