I noticed that the Brave Beta is not saving my preference for blocking ALL fingerprinting in the fingerprinting protection section of settings. If I change it to block all fingerprinting then close the browser, when I open Brave back up and go to settings, my selection has reverted to only blocking 3rd party fingerprinting again. Clean install of W10 1809 x64 and Brave Beta 0.55.11.
This will be fixed in the next build. The issue is already reported and can be tracked here
