Seeing the "Your browser is being managed by your organization" notification at the top of the Settings page is in most cases caused by (security) software that uses GPO policy rules or that uses a policies.json file in the distribution folder in the profile folder to inject their root certificate (ImportEnterpriseRoots) in Firefox to be able to hook into your internet connection and that needs to prevent getting connection not trusted error messages. You can click the "Your browser is being managed by your organization" notification or open the <b>about:policies</b> page to see if policies are active and if errors are reported. *https://support.mozilla.org/en-US/kb/see-active-policies-firefox-enterprise
