Thank you for your feedback. I fully understand that the faulty display of the menu and the conflict with the plugin causes displeasure.
We analyzed the error and found that the display error is caused by a malfunction of the Firefox plugin Privacy Badger. The plugin blocks stylesheets/scripts of our menu plugin for no reason.
It would be a great help, if you report the malfunction to Privacy Badger.
Of course, we do not want to be a data leech. But we do want to understand how our website is used and how we can improve it for our users.
Please contact us, if you notice anything else. Although sometimes it takes a while before we are able to look at but feedback and hints are a great opportunity to us to recognize mistakes and improvement options.
I wish you a great day.
