This is a simple plugin to disable the back button: [dbb /].
This is optimally used for surveys or funnels that you do not want people backing out of. It prevents the back button from being used by employing a small script that quickly replaces the location context of the page and beffudles the browser.
Redux Option panel included allows you to enable this functionality sitewide as well as disable it for logged in users.
