I'm into watching telemetry data using tools like Pihole, Wireshark, DNSLookupView. Firefox is the only browser which does not invoke spontaneous connections and gives the user the Freedom to inspect and clear the cookie data. Google notoriously creates VPN tunnels to hide what it is sending and receiving. Your browser preference might determine many people's privacy if the narrative is limited to not so important things to me like speed and ease of use.
