Preventing Mixed Content Security Warnings
When an HTTPS web page includes sub-resources (images, scripts, stylesheets, fonts) loaded over unencrypted HTTP, modern browsers block the assets and revoke the green padlock, displaying a 'Not Fully Secure' warning. Our tool identifies all insecure assets on the scanned page.
❓ Frequently Asked Questions
What is the difference between passive and active mixed content?
Passive mixed content includes images and audio files loaded over HTTP (often shown with a warning). Active mixed content includes scripts, stylesheets, and iframes, which browsers block completely.
