Firefox addon which refreshes the tap and auto resend data - post

Question

I'm trying make a firefox add-on, which reloads a page automatically under some conditions.
First I add a contentScript to a tab to get some information on the page in my addon
tab.attach({
contentScript:self.port.emit...
I have it working to the point of the refresh with
tab.reload();
but then an alert pops up every time "if it should resend data".
I want to resend the data automatically.
How and where do I do it? In the add-on or in the contentScript?
Has it to do with the Load Flags constant?

This clicks the accept button when the prompt opens. But you see the prompt window for like a couple hundred ms.
i had to use setTimeout with 0 wait time other wise the aDOMWindow.args property and aDOMWindow.Dialog and a bunch of other stuff would be undefined or null so weird. But this works:
var stringBundle = Services.strings.createBundle('chrome://browser/locale/appstrings.properties');
try {
windowListener.unregister();
} catch (ignore) {}
var windowListener = {
//DO NOT EDIT HERE
onOpenWindow: function(aXULWindow) {
// Wait for the window to finish loading
let aDOMWindow = aXULWindow.QueryInterface(Ci.nsIInterfaceRequestor).getInterface(Ci.nsIDOMWindowInternal || Ci.nsIDOMWindow);
aDOMWindow.addEventListener('load', function() {
aDOMWindow.removeEventListener('load', arguments.callee, false);
windowListener.loadIntoWindow(aDOMWindow, aXULWindow);
}, false);
},
onCloseWindow: function(aXULWindow) {},
onWindowTitleChange: function(aXULWindow, aNewTitle) {},
register: function() {
// Load into any existing windows
let XULWindows = Services.wm.getXULWindowEnumerator(null);
while (XULWindows.hasMoreElements()) {
let aXULWindow = XULWindows.getNext();
let aDOMWindow = aXULWindow.QueryInterface(Ci.nsIInterfaceRequestor).getInterface(Ci.nsIDOMWindowInternal || Ci.nsIDOMWindow);
windowListener.loadIntoWindow(aDOMWindow, aXULWindow);
}
// Listen to new windows
Services.wm.addListener(windowListener);
},
unregister: function() {
// Unload from any existing windows
let XULWindows = Services.wm.getXULWindowEnumerator(null);
while (XULWindows.hasMoreElements()) {
let aXULWindow = XULWindows.getNext();
let aDOMWindow = aXULWindow.QueryInterface(Ci.nsIInterfaceRequestor).getInterface(Ci.nsIDOMWindowInternal || Ci.nsIDOMWindow);
windowListener.unloadFromWindow(aDOMWindow, aXULWindow);
}
//Stop listening so future added windows dont get this attached
Services.wm.removeListener(windowListener);
},
//END - DO NOT EDIT HERE
loadIntoWindow: function(aDOMWindow, aXULWindow) {
if (!aDOMWindow) {
return;
}
if (aDOMWindow.location == 'chrome://global/content/commonDialog.xul') {
var repostString = stringBundle.GetStringFromName('confirmRepostPrompt');
var repostStringFormatted = stringBundle.formatStringFromName('confirmRepostPrompt', [aDOMWindow.Application.name], 1);
aDOMWindow.setTimeout(function() {
console.log('setimeout val 00:', aDOMWindow.args)
//aDOMWindow.args and aDOMWindow.Dialog is not available till after setTimeout of 0 so weird
if (aDOMWindow.args.text == repostString || aDOMWindow.args.text == repostStringFormatted) {
console.log('this is resend prompt so accept it');
//aDOMWindow.Dialog.ui.button0.click(); //doesnt work
//aDOMWindow.Dialog.onButton0(); // doesnt work
//aDOMWindow.ondialogaccept(); //doesnt work
var dialog = aDOMWindow.document.getElementById('commonDialog');
var btnAccept = aDOMWindow.document.getAnonymousElementByAttribute(dialog, 'dlgtype', 'accept');
btnAccept.click();
console.log('clicked');
}
}, 0);
}
},
unloadFromWindow: function(aDOMWindow, aXULWindow) {
if (!aDOMWindow) {
return;
}
}
};
windowListener.register();
open scratchpad. set environemnt to browser. run the code. refresh a page to get prompt you'll see it get clicked.
