Hi, i want to standard uncheck the checkbox "Remember this decision" for pfx certificates. We use several certificates on one specific website and if the user forgets to uncheck, he'll panic because of the missing window that contains the other certificates. The key security.remember_cert_checkbox_default_setting under about:config works,... unfortunately I'd like to rollout the setting for the whole company,..... and the Dword reg key "HKEY_LOCAL_MACHINE\Software\Policies\Mozilla\lockPref\security.remember_cert_checkbox_default_setting" set to "0" seems to have no effect on the setting after reboot... I appreciate your help. Installed FF version is 91.3.0esr Kind regards Tom
