Security readout for executives and security teams

This issue affects Mozilla Firefox before 44.0. A malicious website could manipulate the protocol-handler dialog so one click triggers an unintended action where Firefox expected a double-click. The main business risk is user deception on outdated browsers, not server compromise. Exposure is likely limited to endpoints still running Firefox before 44.0 or old distro-packaged Firefox builds covered by Ubuntu, openSUSE, or Gentoo advisories. Treat this as endpoint hygiene unless legacy browsers remain in use. It is old and interaction-dependent, but outdated browsers can still create avoidable phishing and social-engineering risk. Mitigation focus: Upgrade Firefox to version 44.0 or later.; Apply relevant Ubuntu, openSUSE, or Gentoo browser security updates.; Check Mozilla guidance for any environment-specific remediation details..
