ok sorry, for your OS the path where these settings are determined might be HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Tracing\firefox_RASAPI32

if the "enable"-preferences are set to 1 you might want to turn them to 0. i've attached a screenshot on how it looks for me without having done modifications.
