People who throw rocks shouldn't live in glass houses.
Mobile client ads on the home screen, heavily pushed VPN service, forced integration with networked bookmark services, "experiments" that don't check for privacy issues, default search using Google, and a long history of being reactive, not proactive, when it comes to privacy issues - these are just a handful of the problems that Firefox is currently mishandling.
Firefox is in many ways better than Chrome, Safari, and Edge, but it's not exactly a shining paragon of privacy and ethics either. I'd personally prefer that you clean up your house first, please.
