Name of the Vulnerable Software and Affected Versions Firefox versions prior to 63

Description The issue arises when a website loaded over HTTPS loads a favicon resource over HTTP, resulting in the mixed content warning not being displayed to users. This could potentially allow a remote attacker to conduct spoofing attacks by exploiting the lack of a mixed content warning.

Recommendations For versions prior to 63, update to version 63 or later to resolve the issue. As a temporary workaround, consider restricting access to HTTP resources for favicon loading until a patch is available.
