 At the highest security level JavaScript for webpages is disabled, so
 these features cannot be used for fingerprintina and expluatation. But a
 large part of the browser is written in JS itself and disabling this
 features slows the web browser down. I suggest to enable them for the
 highest security mode as a temporary solution and use 2 different settings
 or store there numbers as bit flags to control these features for frowser
 GUI and webpages separately, if it is possible.
