清单JSON文件。像这样：

Did you allow it in your manifest JSON file. Something like this:

manifest.json
$ b

manifest.json

 {
   "name": "My Extension",
   "content_scripts": [{
     "js": ["jquery.min.js", "YourJavaScriptFile.js"],
     "matches": ["http://*/*", "https://*/*"]
   }]
 }

但只是给出了基本的想法。

There are required fields I left out, but just giving the basic idea.
