Question

是否可以使用Firefox扩展创建OS浮动窗口？这样当浏览器失去焦点时窗口就会出现。谷歌搜索没有带来太多。只需要一些教程/写一下。

目标操作系统 - Mac OS X，如果重要的话。

如果你觉得这个问题很愚蠢，我道歉。起初我想知道是否可行和可行。任何想法都表示赞赏。

创建弹出窗口的核心代码是一个名为＆＃39; createPanel＆＃39;在line 149：

createPanel: function() {
   let browser = getMostRecentBrowserWindow();
   let doc = browser.document;

   this.panel = doc.createElementNS(XUL_NS, "panel");
   this.panel.setAttribute("id", "pixel-perfect-panel");
   this.panel.setAttribute("noautohide", "true");
   this.panel.setAttribute("titlebar", "normal");
   this.panel.setAttribute("noautofocus", "true");
   this.panel.setAttribute("label", Locale.$STR("pixelPerfect.title"));
   this.panel.setAttribute("close", "true");
   this.panel.style.border = "0";

   this.panelFrame = doc.createElementNS(XUL_NS, "iframe");
   this.panelFrame.setAttribute("type", "content");
   this.panelFrame.setAttribute("border", "0");
   this.panelFrame.setAttribute("flex", "1");

   // xxxHonza: unregister listeners?
   DomEvents.on(this.panel, "popuphidden", this.onPopupHidden);
   DomEvents.on(this.panel, "popupshown", this.onPopupShown);

   this.panelFrame.setAttribute("src", self.data.url("./popup.html"));
   this.panel.appendChild(this.panelFrame);

   let container = doc.getElementById("mainPopupSet");
   container.appendChild(this.panel);

   // Load content script and handle messages sent from it.
   let { messageManager } = this.panelFrame.frameLoader;
   if (messageManager) {
     let url = self.data.url("popup-frame-script.js");
     messageManager.loadFrameScript(url, false);
     messageManager.addMessageListener("message", this.onMessage);
     messageManager.addMessageListener("sdk/event/ready", this.onPanelReady);
   }

   return this.panel;   
},
