Prevent browser changes with Public Fox. It is is a Firefox extension that allows you to block some of the settings and prevent other users who do not have permission to make any change into the Firefox setting. You can lock the bookmarks, add-ons window, Firefox options, about:config dialog and downloads.
Public Fox blocks users from downloading unwanted files. Please note that only downloads with defined extensions will be locked, just add a listing of extensions separated by “,” to the list and enable lock downloads for this to work.
It also includes a URL blocking feature. For people who want to block certain sites, blacklist it.
A password is required to override block, so if people tried to access about:config, options, history, add a bookmark, download or access a file extension, a prompt appears and a password to override it is needed. Otherwise, the browser blocks access to that.
