I'm trying to add a script tag to every dom page through privileged chrome, so far i'm able to get the first pageload of a tab, but after that, the script does nothing, I'm using Firefox Nightly 44.0. What am i doing wrong???
Documents I'm following:

<script type="application/x-javascript" src="chrome://browser/content/yyy/x.js" />
chrome://browser/content/yyy/x.js
var myExtension = {
init: function() {
// The event can be DOMContentLoaded, pageshow, pagehide, load or unload.
if(gBrowser) gBrowser.addEventListener("DOMContentLoaded", this.onPageLoad, false);
},
onPageLoad: function(aEvent) {
var doc = aEvent.originalTarget; // doc is document that triggered the event
var win = doc.defaultView; // win is the window for the doc
// test desired conditions and do something
// if (doc.nodeName != "#document") return; // only documents
// if (win != win.top) return; //only top window.
// if (win.frameElement) return; // skip iframes/frames
alert("page is loaded \n" +doc.location.href);
}
}
window.addEventListener("load", function load(event){
window.removeEventListener("load", load, false); //remove listener, no longer needed
myExtension.init();
},false);

您希望使用loadFrameScript
参数为true来收听未来的网页。以下是示例:https://github.com/mdn/e10s-example-addons/tree/master/run-script-in-all-pages
globalMM.loadFrameScript("chrome://modify-all-pages/content/frame-script.js", true);
要阻止它在新标签中加载,您必须使用removeDelayedFrameScript
github链接还显示了如何使用addon-sdk内容脚本执行此操作的示例。
