Here is something that will change all of that! We all know that Firefox, Opera or other alternative browsers should be used instead of Internet Explorer. For security, speed, usability, and many more reasons. But people in large networks (e.g. school boards) are reluctant to installing Firefox because they are scared that kids can override the settings and disable the proxies and stuff. They are familiar with Group Policy Editor with Internet Explorer because apparently it is easier because it is a Microsoft technology.
Public Fox - time to show a more manageable Firefox to the world. Some of these certain options are disable-able:
Options panel
about:config panel
Downloads
Adding bookmarks
History
Add-ons
Also, it includes a feature for URL blocking, either a whitelist or a blacklist. For people wanting the browser to visit certain sites, whitelist it. For people wanting to block certain sites (most people), blacklist it. It's that easy!
A password is required to override block, so if people tried to access about:config, options, history, add a bookmark, download a file or access the extensions, a prompt appears and a password to override it is needed. Otherwise, the browser blocks access to that. Very easy, eh?
I have found this useful to introduce to the school and I hope they will get Firefox soon. So see if it is useful to any networks that you work in!
