如何以编程方式将选项卡移动到firefox Addon-SDK扩展中的另一个窗口？

虽然看起来您可以通过更新选项卡.index属性来更改窗口中选项卡的顺序,但它看起来不像 tabs api直接支持将选项卡移动到另一个窗口.

我错过了什么吗？有可行的解决方法吗？

可以通过低级模块窗口/工具来实现.下面的示例在每个打开的窗口中复制活动选项卡

const { getMostRecentBrowserWindow, windows: getWindows } = require("sdk/window/utils");

const { ActionButton } = require("sdk/ui/button/action");

var button = ActionButton({
  id: "duplicatetab-button",
  label: "Duplicate tab",

    var xulwindows = getWindows("navigator:browser");
    var xulactivewindow = getMostRecentBrowserWindow();
    var xulactivetab = xulactivewindow.gBrowser.selectedTab;

    xulwindows.forEach(function(win){

      var duplicatedtab = win.gBrowser.duplicateTab(xulactivetab);
      win.gBrowser.moveTabTo(duplicatedtab, 0); // the second argument is the index
    });
  }
});
