Firefox permission to URL doesn't work in browser extension

问题

I created Chrome extension and it works as I expected. Actually, it periodically sends http request to my server. But when I tried to run it in Firefox, I've got such an error:

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at <my_server_ip>:8080/. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing).

My application listens for incoming requests at server_ip:8080
For making requests to my server from chrome extension, I add such entry to manifest.json:

  "permissions": [
    "http://server_ip:8080/*"
  ],

Suddenly, it doesn't work in Firefox and I can't understand why. I tried a workaround (found in this article):

  "permissions": [
    "<all_urls>"
  ],

And the problem with CORS disappeared. But I want to give permissions only to my resourse - server_ip:8080

How I need to put a rule in permissions entry to make extension work in Firefox?

回答1:

To elaborate on wOxxOm's comment you only need this for your URL permission

"permissions": [
    "http://server_ip/*"
],
