AddToAny With A Strict CSP

Use a nonce

1. Generate a nonce per request, for example:
   MTc2MTU5ODkzLDM4Mzg5NTc1Mg==
2. Include the nonce in your strict CSP:
   Content-Security-Policy: script-src 'nonce-MTc2MTU5ODkzLDM4Mzg5NTc1Mg=='
3. Add the nonce attribute to your AddToAny <script> tag like so:
   <script async nonce="MTc2MTU5ODkzLDM4Mzg5NTc1Mg==" src="https://static.addtoany.com/menu/page.js"></script>
