    },

}

chrome.runtime.onInstalled.addListener(function() {
  chrome.declarativeNetRequest.updateDynamicRules({
    rules: [
      {
        id: "my_rule",
        action: { type: "remove" },
        condition: { urlFilter: ".*" }
      }
    ],
    removeRuleIds: ["append_header_rule"],
    addRules: [{ id: "append_header_rule", action: { type: "modifyHeaders", responseHeaders: [{ header: "Custom-Header", value: "My-Value" }] }, condition: { urlFilter: ".*", resourceTypes: ["main_frame"] } }]
  });
});
