Is this Android? You're probably hitting #283. Can you try the suggested workaround (at the beginning of your code, before you use Cloud Firestore):

const originalSend = XMLHttpRequest.prototype.send;
XMLHttpRequest.prototype.send = function(body) {
  if (body === '') {
    originalSend.call(this);
  } else {
    originalSend.call(this, body);
  }
};

There's a pull request to fix this in React Native, but it hasn't been merged yet: facebook/react-native#17940
