Twitter widget not saving

Hello – I have been trying to add the Twitter widget code I have directly from Twitter into a text widget in a sidebar and while my other text widgets save fine, this one just keeping having the round save icon going and going and is not saving.
Please help ??
I am on a Mac 10.5.8 and have tried on both Firefox and Safari and same experience with both. Thank you!

Here is the Twitter code just in case:

<script src="https://widgets.twimg.com/j/2/widget.js"></script>
<script>
new TWTR.Widget({
  version: 2,
  type: 'profile',
  rpp: 3,
  interval: 6000,
  width: 250,
  height: 300,
  theme: {
    shell: {
      background: '#a4a5a6',
      color: '#ffffff'
    },
    tweets: {
      background: '#ffffff',
      color: '#02a1d1',
      links: '#e87b07'
    }
  },
  features: {
    scrollbar: false,
    loop: false,
    live: false,
    hashtags: true,
    timestamp: true,
    avatars: false,
    behavior: 'all'
  }
}).render().setUser('jordanbenshea').start();
</script>
