Ensure 'Do not allow preferences to be changed' is set to 'Enabled'

MittelStufe 1Automatisiertfirefox

Beschreibung

This policy setting configures if the Firefox pop-up blocker settings can be changed by the user. The recommended state for this setting is: Enabled. Rationale: By enabling the pop-up blocker, all pop-ups will be blocked which will guard a user against malicious attacks launched using a pop-up window. Audit reads the Group Policy registry value and prints 'compliant', 'unset' (policy not configured, reported as FAIL) or the non-compliant value. Registry value: HKLM\SOFTWARE\Policies\Mozilla\Firefox\PopupBlocking:Locked (REG_DWORD); compliant when it is 1. Remediation writes 1 locally; in a domain set it through the ADMX so Group Policy does not revert it.
