Readonly windowsOn Windows, chrome-privileged notifications -- i.e., those with a
non-actionable principal -- can have actions that are activated by Windows
and not processed by Firefox. When windowsSystemActivationType is true,
we request Windows to process action. At the time of writing, Windows
recognizes the following actions:
action="dismiss" dismisses the alert entirely.action="snooze" snoozes the alert, generally making it disappear before
reappearing a Windows-determined amount of time later.On non-Windows, this field is ignored.
Optional aInstancePtr: objectA run time mechanism for interface discovery.
NS_OK if the interface is supported by the associated instance, NS_NOINTERFACE if it is not.
aInstancePtr must not be null.
[in] A requested interface IID
[out] A pointer to an interface pointer to receive the result.
Generated using TypeDoc
