Answer 1

It's because of the improper rules set to firebase storage. You can set the following rule for testing:

service firebase.storage {
  match /b/{bucket}/o {
    match /{allPaths=**} {
      allow read, write;
    }
  }
}

Setting the above rule would open if for public. Hence you have to set appropriate authentication rule for production.
