Firefox has introduced a new feature called the “Trust Panel,” which appears as a unified “Shield” icon in the address bar. This new icon replaces the previous Privacy shield and Secure lock icons, merging both functions into one. Users will see this single Shield icon in the URL bar of the Firefox browser.

As of this writing, the “Trust Panel” is a testing feature in Firefox and is not enabled by default. To activate it, users must adjust the hidden browser preference settings. This guide will explain how to enable this new feature.
As said, the new Trust Panel merges the privacy shield and secure lock icons into a single icon. When users click this icon in the address bar, Firefox displays a fly-out menu with detailed tracking protection information, as illustrated in the screenshot below.
Using the Trust Panel button in the address bar of Firefox browser you can view trackers blocked, secure connection details (verified by Google), option to clear cookies and site data, option to turn On/Off enhanced tracking protection etc.
