Firefox caching to NFS mounted home directories killing disk IO on file server

[Rippl, Steve]

That does look fine.  So the one difference we have is that in
/etc/firefox/prefs we put the 2 lines

pref("general.config.obscure_value", 0);
pref("general.config.filename", "firefox.cfg");

in a separate file we call local-settings.js, rather than within the
firefox.js.  I'm assuming everything in that folder gets read and this
shouldn't make any difference, but it's the only difference I can see at
this point.
