我对Firefox及其扩展很新。有没有类似于使用JavaScript的脚本,每次加载页面时都会运行?我的chrome扩展插入了一个css文件,使用js创建了一个链接标记。如何将其移植到Firefox?

您需要pageMod API。
var pageMod = require("page-mod");
pageMod.PageMod({
include: "*.example.org",
contentScript: 'window.alert("Page matches ruleset");'
});

每次mozIJSSubScriptLoader时,您都可以使用webpage loads执行JavaScript (chrome://myExtension/content/script.js) 。以下是您需要根据chrome目录修改的示例代码
window.addEventListener("load", function load(event){
window.removeEventListener("load", load, false); //remove listener, no longer needed
myExtension.init();
},false);
var myExtension = {
init: function() {
var appcontent = document.getElementById("appcontent"); // browser
if(appcontent){
appcontent.addEventListener("DOMContentLoaded", myExtension.onPageLoad, true);
}
var messagepane = document.getElementById("messagepane"); // mail
if(messagepane){
messagepane.addEventListener("load", function(event) { myExtension.onPageLoad(event); }, true);
}
},
onPageLoad: function(aEvent) {
var doc = aEvent.originalTarget; // doc is document that triggered "onload" event
// do something with the loaded page.
// doc.location is a Location object (see below for a link).
// You can use it to make your code executed on certain pages only.
var loader = Components.classes["@mozilla.org/moz/jssubscript-loader;1"].getService(Components.interfaces.mozIJSSubScriptLoader);
loader.loadSubScript("chrome://myExtension/content/script.js", doc);
// add event listener for page unload
aEvent.originalTarget.defaultView.addEventListener("unload", function(event){ myExtension.onPageUnload(event); }, true);
},
onPageUnload: function(aEvent) {
// do something
}
};

我以前在Firefox上使用Greasemonkey。事实上,Chrome扩展程序最初是作为Greasemonkey的模仿,并且是内容脚本的起源。
