Type: boolean
Note: Applies to: Thunderbird, SeaMonkey
If true, the popup will be shown. If false, the popup will not be shown, but the autocomplete results will still be available. You can set this to false and set the autoFill attribute to true to emulate a Communicator 4.x style autocomplete textbox. The default value is true.
