Address bar Extended Validation (EV) Certificate information
Used to be able to go to about:config, search for and change security.identityblock.show_extended_validation to true. Now I can't. Is there another easy way to show the name and country of the organization that got the EV Certificate on the address bar?
A feedback was sent about this. I think the feedback sent used be posted at http://input.mozilla.org/. Now where does it go and shows up?

An Extended Validation Certificate (EV) is a certificate conforming to X.509 that proves the legal entity of the owner and is signed by a Certificate Authority key that can issue EV certificates. EV certificates can be used in the same manner as any other X.509 certificates, including securing web communications with HTTPS and signing software and documents. Unlike domain-validated certificates and organization-validation certificates, EV certificates can be issued only by a subset of certificate authorities (CAs) and require verification of the requesting entity's legal identity before certificate issuance.
By August 2019, Google Chrome, Mozilla Firefox and Apple Safari web browsers show the verified legal identity in their user interface, either before, or instead of, the domain name, but they plan to remove this distinction in the near future. Mobile browsers typically display EV certificated the same way they do DV and OV certificates. Of the ten most popular websites online, none use EV certificates and the trend is away from their usage.[citation needed]
For software, the verified legal identity is displayed to the user by the operating system (e.g., Microsoft Windows) before proceeding with the installation.
Extended Validation certificates are stored in a file format specified by and typically use the same encryption as organization-validated certificates and domain-validated certificates, so they are compatible with most server and User Agent software.
The criteria for issuing EV certificates are defined by the Guidelines for Extended Validation[1] promulgated by the CA/Browser Forum, a voluntary organization whose members include leading CAs and vendors of Internet software as well as representatives from the legal and audit professions.[2]
To issue an extended validation certificate, a CA requires verification of the requesting entity's identity and its operational status with its control over domain name and hosting server.
Support for this pref has been removed in Firefox 77.
