Current browser security and mixed content
Internet Explorer is retired. Use an up-to-date browser such as Chrome, Edge or Firefox. Browser support for specific SmartCall hardware functions must be verified for your installation.
Chrome
Review site permissions under Settings > Privacy and security > Site settings. If your organization allows insecure-content exceptions for a trusted site, use only an IT-approved exception, not browser-wide security disabling.
Microsoft Edge
Review Site permissions and policies for insecure content. Organizations may restrict these settings. Do not disable browser protection globally.
Firefox
Firefox blocks active mixed content; HTTPS-Only Mode is a separate feature. Request IT support to investigate insecure requests rather than disabling protections in about:config.
Preferred fix: where feasible, update the affected resource to HTTPS rather than bypassing browser protections.
