What does it mean when I have both secure and non-secure (mixed) content?

Secure and non-secure content, or mixed content, means that a webpage is trying to display elements using both secure (HTTPS/SSL) and non-secure (HTTP) web server connections. This happens because we only secure personal and financial data but not the our images.

Note

You can always tell when your data is safe when pages use the prefix HTTPS, while regular webpages use HTTP.
