Something that is more elegant than FF. That one is more of TL;DR. Don't use the FF/IE "View Certificate" button. Proposed info to display: --- BEGIN DIALOG Top Website Identity Website: bugs.kde.org Owner: This website does not supply ownership information. Verified by: Sectigo Limited Expires on: October 18, 2022 Bottom Use table widget to present the certificate. --- END DIALOG P.S. Looking at FF Security tab, it looks that they didn't put much time to it, notice the buttons, to open a new dialog, lack of Ellipsis. I guess FF/MZ have done so intentionally to keep the novice and curious user away from it.
