Stylus is a WebExtension which doesn't yet have an API in Firefox to allow customization of browser UI. In other words none of such styles will work. There's nothing we can do about it.

Try using an additional addon for styling the browser like https://github.com/Cauterite/firefox-userchrome-addon
