We drop IP already when proxying a number of Google services, see https://github.com/brave/brave-browser/wiki/Deviations-from-Chromium-(features-we-disable-or-remove)#services-we-proxy-through-brave-servers https://github.com/brave/brave-browser/wiki/Deviations-from-.... We've used Fastly in the past to drop IP, implemented using VCL. I believe we're using other vendors now as well. Unlikely to use FoxyProxy but the idea is the same. We don't log IPs and don't let them get to us or to Google or other service providers, where possible.
