Firefox附加组件获取发出HTTP请求的DOM窗口

// 获取当前活动的浏览器窗口
var windowMediator = Components.classes["@mozilla.org/appshell/window-mediator;1"]
                               .getService(Components.interfaces.nsIWindowMediator);
var mainWindow = windowMediator.getMostRecentWindow("navigator:browser");

// 获取当前活动标签页的浏览器窗口
var currentTab = mainWindow.gBrowser.selectedTab;
var currentWindow = currentTab.ownerDocument.defaultView;

// 获取当前窗口发出的HTTP请求
var httpRequests = currentWindow.performance.getEntriesByType("resource")
                                            .filter(function(entry) {
                                                return entry.initiatorType === "xmlhttprequest";
                                            });

// 打印HTTP请求的URL
httpRequests.forEach(function(request) {
    console.log(request.name);
});
