The shown message comes from Firebug Lite itself. It is not the page that prevents it from being opened.
If you want to prevent it from opening you may create a Mutation Observer <https://developer.mozilla.org/en-US/docs/Web/API/MutationObserver> and check when the element with the ID FirebugUI is added and remove it immediately. Though note that people can still inspect your page with the built-in DevTools and there is no way to block them from within your website. What is the reason you want to block Firebug Lite from being opened?
