AddToAny With A Strict CSP

Use a nonce

1. Generate a nonce per request, for example:
   MjMwNDMyMzgyLDMxMTQ3MzIyOQ==
2. Include the nonce in your strict CSP:
   Content-Security-Policy: script-src 'nonce-MjMwNDMyMzgyLDMxMTQ3MzIyOQ=='
3. Add the nonce attribute to your AddToAny <script> tag like so:
   <script async nonce="MjMwNDMyMzgyLDMxMTQ3MzIyOQ==" src="https://static.addtoany.com/menu/page.js"></script>
