• if using firefox instead of just the tor browser and have firefox configured to use 127.0.0.1 9050 as a proxy and have the tor service running open firefox and browse to about:config

• Change privacy.resist.Fingerprinting from false to true

• IMPORTANT: All other web browser windows should be closed before opening firefox through proxychains
