Is this about the message you see at the top of the Settings page? Seeing the "Your browser is being managed by your organization" notification at the top of the Settings page can be caused by (security) software that uses GPO policy rules or uses a policies.json file in the distribution folder in the profile folder to inject their root certificate in Firefox in Firefox to be able to hook into your internet connection (ImportEnterpriseRoots) to prevent getting a connection not trusted error message. 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
