[Project_owners] Display right-click context menu programmatically

Hey All,

I'm having trouble trying to display the right-click context menu
programmatically (without having to actually right-click). I continue to get
an exception (see below) that I can't seem to get around and was hoping
someone else might have a better idea/solution. What I've done is setup a
window event listener for "click" that executes my code below. I'm checking
for the left mouse button before attempting to show the right-click context
menu (popup). Any suggestions/help would be great. Thanks.

window.addEventListener("click", doitfunc, false);

function doitfunc(aEvent) {
  if (aEvent.button == 0) {
    var context = document.getElementById("contentAreaContextMenu");
    context.showPopup(document.documentElement, 0, 0, "popup", null, null);

Error: [Exception... "Component returned failure code: 0x8000ffff
[nsIDOMXULDocument_MOZILLA_1_8_BRANCH.popupRangeParent]"  nsresult:
"0x8000ffff (NS_ERROR_UNEXPECTED)"  location: "JS frame ::
chrome://browser/content/browser.js :: anonymous :: line 3932"  data: no]
