Summary

A vulnerability exists in Mozilla's Firefox and Thunderbird products where internal browser event interfaces are exposed to web content due to privileged EventHandler listener callbacks. While web content cannot leverage these interfaces with elevated privileges, their exposure signals the usage of certain browser features, such as the Dev Tools console. This scenario can lead to information leakage and may indicate underlying security risks. Users of affected versions are encouraged to update to the latest releases to mitigate potential threats.
