TrustedForm stores all Certificates and snapshots in a secure (SSL/TLS) environment. However because of this, sometimes not all content is displayed when looking at a snapshot – but there are easy ways to correct this.
First a quick overview on why this occurs. Page content may include secure and non-secure content - and TrustedForm captures both. Additionally, while the captured page may be straight HTTP with no security, the snapshot is shown by TrustedForm over a secure (https) site. When an HTTPS page has HTTP content, that content is considered “mixed”. The webpage that the user is visiting is only partially encrypted, since some of the content is retrieved unencrypted over HTTP. In order to fully display mixed-content pages, you may need to update your browser settings.
Below is information on how to handle mixed-content per browser:
If Chrome detects certain types of content on the page coming from insecure channels, it automatically prevents the content from loading.
Previously there was a shield icon (see below) you could click to allow mixed content.
Beginning with v48, Chrome basically prevents you from allowing mixed content. You'd have to tamper with the inner workings of Chrome and make your browser less secure for all sites. This is obviously not advised.
The better option is to make all your forms HTTPS and encourage Vendors to do the same.
See Google's guide to tracking down and fixing mixed / insecure content.
If a user visits an HTTPS page with Mixed Active Content, they will see a lock with a yellow warning in the location bar. Click on the warning, then the > in the top warning section
Then choose 'Disable protection for now".
Internet Explorer blocks non-secure content by default and is set to prompt you when this is happening. You may see a pop-up that asks if you want to only view the secure content - click 'No' to load the mixed content.

Safari doesn't not show a warning for normal mixed content websites. However if you do have any issues, you can edit your Security Preferences.
