无法从Chrome扩展程序中的后台脚本向内容脚本发送消息

Question

I cannot send message from my background script to content script except i remove the popup.html from the browser action in the manifest.json. Someone help me

background.js

// Called when the user clicks on the browser action.
chrome.browserAction.onClicked.addListener(function(tabs) {
  // Send a message to the active tab
  chrome.tabs.query({active: true, currentWindow: true}, function(tabs) {
    var activeTab = tabs[0];
    chrome.tabs.sendMessage(tabs[0].id, {"message": "clicked_browser_action"});
  });
});

// This block is new! and will be used later
chrome.runtime.onMessage.addListener(
  function(request, sender, sendResponse) {
    if( request.message === "open_new_tab" ) {
      chrome.tabs.create({"url": request.url});
    }
  }
);

content.js

 chrome.runtime.onMessage.addListener( function(request, sender, sendResponse) { if( request.message == "clicked_browser_action" ) { console.log("Congratulations you can now work!"); // This line is new! chrome.runtime.sendMessage({"message": "open_new_tab", "url": firstHref}); } } ); 

manifest.json

  { "name": "Wowprezi lead tool", "version": "1.0", "description": "Extension to find leads and add to sales force!", "author": "Djouonang Landry", "manifest_version": 2, "content_security_policy": "script-src 'self' https://ssl.google-analytics.com; object-src 'self'", "background": { "persistent": true, "scripts": ["js/background.js"] }, "content_scripts": [ { "matches": ["<all_urls>"], "js": ["js/jquery-3.3.1.min.js","js/content.js"], "all_frames": true } ], "browser_action": { "default_popup": "html/popup.html", "default_title": "Find leads" } } 

popup.html - Except this is removed from the manifest.json i cannot send message from background to content.js. Please note i use the console function to check if the message was sent across to the content.js

According to documentation , the chrome.browserAction.onClicked listener is

Fired when a browser action icon is clicked. Does not fire if the browser action has a popup.

(bold type added).

Either remove the browserAction popup or move the code you currently have inside the listener to the popup page script.
