Maybe you did not notice, but if you view your website in Foxfire or Chrome you will see that your favicon no longer appears in the address bar, next to your url address.
This action has been taken by Foxfire and Chrome as a security precaution. While viewing secure https sites, visitors are accustomed to seeing and expect a small paddock icon. This symbol assures them that the site is secure.
However, inadvertently or deliberately, similar icons have been used on non-secure sites, and visitors may be taking a risk by entering their personal information on the non-secure sites.
