When you view or visit a secure website, the site will display an identity button in the Firefox browser, also known as padlock that appears in green. However, there are instances when it might display a gray padlock with a red strikethrough or some yellow warning triangle or a broken padlock.
The Site Identity button or the padlock, under normal circumstances, appears in Firefox’s address bar when you visit a secure website so that you can find out if the connection to the website you are visiting is secure and encrypted. Because of this, it will prevent you from visiting malicious and unsecured websites that may try to obtain personal information from you. This feature is available in the latest Nightly to build 59.0 Firefox web browser although it isn’t enabled by default. You must enable it to help you identify if a website has an unsecured connection in the address bar of your Firefox browser – and this post will show you how to do so. Follow the steps below to enable this feature in your Firefox browser.
Step 1: Open Mozilla Firefox and then in its address bar, type in about:config and then tap Enter to open Firefox’s settings.
Step 2: After you tap Enter, a warning message will pop up – just click on the “I accept the risk” button to proceed. The “about:config” contains ever settings in Firefox which includes the settings for all its installed extensions. Note that the settings that are non-bold are the default settings while the ones that are in bold are the ones that have been changed.
Step 3: From there, in the Search filter box, type in insecure_connection_icon and then tap Enter. After that, it will show you the following preference in the window:
“security.insecure_connection_icon.enabled”
Note: as you can see, this preference is set to “False” by default – so obviously, it is disabled.
Step 4: You have to turn that feature on so you have to double click on security.insecure_connection_icon.enabled preference and set its value to True.

As an alternative, you can also right-click on the preference and select the Toggle option. And so that’s how you enable the security insecure connection icon in the Firefox browser in Windows 10.
