How to change text in Chrome Confirm window "XYZ Website says:"

I have developed extension that generates confirm window on a current open tab after a certain interval of time. Its working fine but I want to change the text "XYZ website says" to my extension name. How can I do this? Is it possible? chrome confirm window

Here is my background code:

var notifyTimer = setInterval(func, 5 * 1000);
console.log('setinterval ran');


function func() {
  let ActiveTab = getCurrentTab();
  console.log(ActiveTab)

}

const confirmWindow = () => {
  let result = confirm("You've been working for too long on Chrome. Would you like to take a break?");
return result;
}

async function getCurrentTab() {
  let queryOptions = { active: true, lastFocusedWindow: true };
  let [tab] = await chrome.tabs.query(queryOptions);
  console.log(tab.url)
  //alert(" Hello!")
  // SOME CODE TO GENERATE CONFIRM WINDOW or ALERT
  chrome.scripting.executeScript({
    target: { tabId: tab.id },
    func: confirmWindow
  });

  return tab;
}
Solution

  • It's not possible to fully customise this text - since the UI is controlled by the browser it's important that it's correctly attributed, and as a result the browser is responsible for choosing this string. However, you can have your extension name appear here:

    • In MV2, make sure you call alert from the background page rather than a content script.
    • In MV3, call alert from an offscreen document. One caveat here is that offscreen documents must be created with a reason and I don't think any of the currently supported reasons are appropriate for alerts. If your alert is part of a larger operation, this could work, but otherwise this approach may not be suitable.
