  <p>It gives the following error in the browser console when executing "ionic serve"</p>
  
  <blockquote>
    <p>Refused to load the image '<a href="http://localhost:8100/favicon.ico" rel="nofollow noreferrer">http://localhost:8100/favicon.ico</a>' because
    it violates the following Content Security Policy directive:
    "default-src 'none'". Note that 'img-src' was not explicitly set, so
    'default-src' is used as a fallback.</p>

  <p>Thanks for your time!</p>
