Was passing it long time ago just fine but now I have no idea what happened in my Firefox 74.0.1 (64bit) (Win 10) - something doesn’t work anymore (even on clean profile), sDNS and eSNI seems dead ? I’m out of ideas cuz about config settings are still the same:
network.trr.mode = 3 (tried 2 too)
network.security.esni.enabled = true
maybe my ISP (Russia) strengthened DPI censureship settings and blocked things?
