Just like a computer with multiple users require restriction and rules on what each user can do on the shared computer, a browser, which is the gateway to the world wide web, requires user access restrictions too.
Public Fox is an addon for Firefox that allows the computer administrator to lock down various areas of the browser on a shared PC. Public Fox password protects the following sections in Firefox:
# Lock downloads: Users can’t download files with specified extensions using Firefox, like EXE, BAT and anything that would like to add. You can also add XPI to prevent installation of new addons.
# Lock addons window: Users can’t uninstall addons from Firefox
# Lock Options and about:config.
# Lock History sidebar, Bookmarks addition and Clear Private data option.
# Blacklist certain websites from opening
Trying to access these areas prompt for a password.
There are a few issues with this addon though, like the bookmark block didn’t work on my Firefox (version 3.0.1) and one user said that the addon blocking didn’t work in version 3.0.8. Every new update of Firefox is most likely breaking the security restrictions of this addon. Either the developer has to keep up with the fixes or users who want to use this tool will need to downgrade a couple of versions.
