We'll create fresh WordPress site with WP LibreJS installed. You have 20 minutes to test the plugin after that site we'll be deleted.
WP LibreJS module provides compatibility with the GNU LibreJS browser plugin.
It adds tags to pages indicating that all JavaScript is GPL v3+. It will only discover JavaScript files as they are loaded by an administrator user, so every time you add new JavaScript links you will have to load a page that have those links, with an administrator user logged in.
Note: you should only install this module if you are sure all JavaScript on your site is in fact GPL v3+ compatible.
WP LibreJS is free software and it gives you freedom!
