我正在制作Chrome扩展程序，用于从网页中删除广告。这是我的代码：

manifest.json：

{
   "manifest_version":2,
   "name":"Ad Killer",
   "description":"A Basic program for blocking ads",
   "version":"0.5",
   "permissions": ["activeTab"],
   "background":{
      "scripts":[
      "background.js"]
   },
   "content_scripts":[
      {
         "matches":[
            "<all_urls>"
         ],
         "js":[
            "jquery-3.2.1.min.js"

         ]
      }
   ],
   "applications":{
      "gecko":{
         "id":"{99f660be-10c4-4cc8-9205-72dd45f156b9}"
      }
   },
   "browser_action":{
      "default_icon":"ad128.png",
      "default_title":"Ad Killer"
   }
}

我的background.js：

var enable = false;
enable = enable ? false : true;
chrome.browserAction.onClicked.addListener(function (tab) {
    enable = enable ? false : true;
    if(enable){
    chrome.browserAction.setBadgeText({ text: 'ON' });
    //location.reload();
     chrome.tabs.executeScript(null, { file: 'content.js' }); 
} else {
    enable = false;
    chrome.browserAction.setBadgeText({ text: 'OFF' });
    chrome.tabs.executeScript(tab.id, {code:"location.reload(false);"});
    }
});

最后，我的content.js：

var elems = document.getElementsByTagName("iframe");
var ob2 = $("div[class^='OB_AR_'],div[id*='OB_AR_']");
var ob3 = $("div[id^='outbrain_widget_13'],div[id*='outbrain_']");

var google_ads = $("div[id^='google_ads_iframe_'],div[id*='google_ads_iframe_']");

所以这是我的问题：基本上，当用户点击图标时，它会显示一个徽章，并删除用户访问过的每个页面的广告，直到用户再次点击该图标把它关掉。问题是，如果我打开它并转到另一个页面，广告就会显示出来。是否有一种方法可以在用户单击图标将其打开时将脚本注入每个页面？ 任何帮助表示赞赏。
