I suppose if you disabled firefox from looking at the users home
directory (either in Documents and Settings or /home, whichever platform
you are on) for the Application Data\Mozilla or .mozilla folders, you
could then write protect the application directory to prevent the
installation of plugins.

Another problem, especially on windows is that >90% of the users out
there run with local admin privileges which means that they can access
all folders on the local machine.  The bulk of the remaining users
generally run with "Power User" privileges which still gives them write
access to program files.

Actually, the more I think about this the harder it seems.  I know for
my clients, since disabling USB keys is not an option, anyone could
bring a portable version of Firefox in and then run that off of a
pendrive.

What we settled on instead is an authenticating proxy (squid) that
requires an Active Directory account (or really any authentication
scheme you happen to have locally).  We then don't need to worry about
cross platform support and any problem users are easily disabled.

Of course you could always compile your own version of firefox without
plugin support.  You would also have to build for each platform that you
support.  Seems like a lot of effort for a marginal gain, especially
when you consider usb drives.
