 This plugin is designed to function securely with both WordPress and WordPress Multisite. When the JavaScript Embed Code is entered on the settings page, the user account id is extracted from the embed code and the correctly formed Typekit Embed Code is included in the site header, so it is not possible to use the Embed Code field to include arbitrary JavaScript. The Custom CSS field is also filtered, and doesn't allow any HTML code to be entered.
 
-If the website is using HTTPS/SSL, the SSL version of the Typekit embed code is automatically used instead.
