Heh, it's a total joke on Internet Explorer 5.5 (which is what I've got in front of me). New windows still have full widgets, and you can open them via Ctrl-N, or right-click->"open in new window".

Netscape 4 isn't much stronger: there's no right-click at all, but alt-arrows (for forward and back) work. Also, ctrl-N opens a new window, which has an empty "tear-off" toolbar at the top. "Minimizing" this by clicking on its tab, and maximizing it again, gives a location bar. Not that you need this, since Ctrl-O opens a "location" dialog box, on both browsers

Also, on both browsers, Ctrl-O offers a button which brings up the file browser, granting access to the file system.

w.r.t. ccunning's WU on iCab, below, a kiosk typically has a keyboard locked into place. Simply remove the Command or Option keys and attach a block of wood in its place to keep people from using a pencil to press the button. I've always heard good things about iCab, and this confirms that it's a well-engineered piece of software.

JayBonci: On Linux, it is fairly easy. I think netscape-remote does something predictable if Netscape is crashed (but not exited). Thus, a shell-script can take care of the restart issue. Now, set up xdm not to ask for log in info (I assume this is possible), and set a full-screen netscape as the only window (don't even have a window-manager). chmod a-rw ~kiosk and everything in it. You're set.
