    • Hi,

      I am looking at it now.  Can you provide a complete repro for this?  I.e. including the manifest file you are using and the URL’s?  I will create one myself but this will save time if I have any questions related to the manifest file settings, etc.

      Also, can you send the request and response headers for the initial request?

      Appreciate the help,


    • Can you also provide the error message you are seeing and from where you are seeing it?

      Which version of Windows 10 are you using.

    • Thanks a lot Steven,
      Below are the details,
      "manifest_version": 2,
      "author": "MYEXT",
      "name": "myext Plugin",
      "description": "Downloads the document",
      "permissions": [":///*", "tabs","downloads", “activeTab”],

      "browser_action": {
      "default_icon": { "48": “favicon.png” }
      "content_scripts": [
      "matches": ["http:///","https:///"],
      "js": [“jquery-3.2.1.min.js","content.js”]
      "background": {
      "scripts": [“back.js","jquery-3.2.1.min.js”],"persistent":false
      } ,
      "externally_connectable": {
      “matches": ["://.myext.com/*”]


      And the Error is:

      {readyState: 0, status: 0, statusText: "error"}

    • And windows 10 version is :
      OS Name Microsoft Windows 10 Enterprise
      Version 10.0.15063 Build 15063

    • I am getting these messages on background page of extension!

    • Any updates on this?
