What did you expect to see?

The xhr.progress event.load should have returned bytes:

function handleEvent(e) {
  log.textContent = `${log.textContent}${e.type}: ${e.loaded} bytes transferred\n`;
}

ran the example from the article https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/load_event

Using the base example rather than the modified version you have shared, I see that the results are identical in both Chrome and Firefox. It is probable that the issue you are experiencing is related to the resource you are trying to load rather than an issue with the browser.
