textbox.minResultsForPopup

minResultsForPopup Obsolete since Gecko 1.9.1
Type: integer
The minimum number of results that must be returned for the popup to be displayed. The default value is 1. A zero value will always open the popup unless the textbox is empty. This can be used to display additional items that are not autocomplete results. As of Gecko 1.9.1, this attribute is now always specified in lower case.
