Page XY doesn work (right). Why?
Some Websites need Cookies and/or JavaScript to work. You can activate this by deselecting the checkboxes. Anyway some pages which need JavaScript won’t work at all. This is because JavaScript is a big risk for anonymity. If JavaScript is interpreted on client-side (on your Computer), it can easily read out your real IP and bypass every anonymization! That’s why JavaScript is interpreted on server-side. Sadly this doesn’t work with all websites.
