I'm a big a firefox fanboy as the next guy. But they didn't send it out disabled. I never opted into studies but the plugin was enabled on my browser. If mozilla wants to retain users who value privacy, they need to put their money where their mouth is and not sell them out for ARG $$.

I'm not the only one, and this apology doesn't admit to that. Therefore it's as good as, if not worse than, no apology. Definitely considering switching back to chrome.
