Using nsIFilePicker
const nsIFilePicker = Components.interfaces.nsIFilePicker; var fp = Components.classes["@mozilla.org/filepicker;1"] .createInstance(nsIFilePicker); fp.init(window, "Dialog Title", nsIFilePicker.modeOpen); fp.appendFilters(nsIFilePicker.filterAll | nsIFilePicker.filterText); var rv = fp.show(); if (rv == nsIFilePicker.returnOK) { var file = fp.file; // work with returned nsILocalFile... }
