How to get the tab Index of the right clicked inactive tab?

Who to get the tab Index of the right clicked tab that fires the Tab context-menu. Tab is NOT the active tab (not the selectedIndex)?

As an example. "Close Tabs to the Right" in Tab context menu works regardless of which tab (active/not-active) tab is right-clicked. How does it get the correct tab index?

Solution

  • Listen for for the popupshown event of the tabContextMenu element.

    Since this a restartless addon I assume that you already have a reference to the ChromeWindow.

    var tabContextMenu = chromewin.document.getElementById("tabContextMenu");
tabContextMenu.addEventListener("popupshown", function(){
  var rightclickedtab = chromewin.TabContextMenu.contextTab;
  // now proceed as you wish
}, false);

    You can also add your own menu item and listen for its command event.

    In any case, remember to cleanup when your extension gets unloaded.
