Rather than chrooting (though that may be a good idea still), you
should investigate how to restrict what options are availible to the
user in firefox. Here we have a bank of thin clients that let the user
run firefox but have all but the file and edit menus disabled. In the
about:config page, there are options set to not store anything to
disk. The config files are also read only, as far as I can tell.
