The next Firefox major release will update the security indicators in the address bar and add a privacy icon to signal privacy threats on loaded pages. The changes fix on the icons indicating an in/secure connection, site identity, as well as tracking and cryptomining activity. Mozilla wants to still provide this information for those that want it and hide it for the majority of users that do not need it. Google Chrome gave up on the ‘Secure’ indicator for HTTPS sites in version 69, released a little over a year ago.
