Allow connections to your web site:
"permissions": [ "http://*.radionsm.lv/" ],

Chrome Extensions have two “modes” when making cross-domain XHR requests:

1) If the area is within the “permissions” part of the manifest.json file – The request doesn’t have an “Origin” header, and it at all times succeeds.

2) If the area will not be in “permissions” – The request consists of an “Origin” header with the worth “chrome-extension://…” This signifies that the request is a CORS request, and the response should have a sound Access-Control-Allow-Origin header with a purpose to succeed.

You might want to arrange permissions in manifest.json:

  "permissions": [
    "https://example.com/" // if you need a particular site
    "<all_urls>"           // if you need any site (this will incur 
                           // manual review process in Chrome web store, mind you)
  ],

Please notice, that since Chrome 85 extn content material scripts are subject to the same CORS policy as vanilla internet requests. Which implies that the one option to do cross-site requests in extn now’s to fetch in background script and go the consequence to content material script:

// Old content material script, making a cross-origin fetch:
var itemId = 12345;
var url = "https://another-site.com/price-query?itemId=" +
         encodeURIComponent(request.itemId);
fetch(url)
  .then(response => response.textual content())
  .then(textual content => parsePrice(textual content))
  .then(value => ...)
  .catch(error => ...)

// New content material script, asking its background web page to fetch the info as a substitute:
chrome.runtime.sendMessage(
    {contentScriptQuery: "queryPrice", itemId: 12345},
    value => ...);

// New extension background web page, fetching from a identified URL and relaying information:
chrome.runtime.onMessage.addListener(
  operate(request, sender, sendResponse) {
    if (request.contentScriptQuery === "queryPrice") {
      var url = "https://another-site.com/price-query?itemId=" +
              encodeURIComponent(request.itemId);
      fetch(url)
          .then(response => response.textual content())
          .then(textual content => parsePrice(textual content))
          .then(value => sendResponse(value))
          .catch(error => ...)
      return true;  // Will reply asynchronously.
    }
  });
