title: replace company icons from a website globally
body: <p>If a company changes its icon (e.g., FB to Meta), will a one-liner work to replace all old icons with new ones? Like this:</p>
  <pre><code>Array.from(document.getElementsByClassName(&quot;old-icon&quot;)).forEach((item, ind) =&gt; item.src = 'newIcon.png')
  </code></pre>
  <p>Any other factors we should consider?</p>
