You’re likely seeing high DNS traffic because of a misconfigured setting or a problematic extension. Try disabling extensions and checking your DNS settings. Also, monitor for any unusual network activity.
Mozilla rents server storage on Google Cloud servers (mozgcp.net). This specific URL seems to be about the captive portal detection.
This is about network detection done by Firefox on startup and later at regular intervals to see whether it can reach detectportal.firefox.com. See Network Detection:
