AddToAny With A Strict CSP

Use a nonce

1. Generate a nonce per request, for example:
   MjcxNjAxMzY3OCwzMjE4OTcwNzE5
2. Include the nonce in your strict CSP:
   Content-Security-Policy: script-src 'nonce-MjcxNjAxMzY3OCwzMjE4OTcwNzE5'
3. Add the nonce attribute to your AddToAny <script> tag like so:
   <script async nonce="MjcxNjAxMzY3OCwzMjE4OTcwNzE5" src="https://static.addtoany.com/menu/page.js"></script>
