Developer Plugin host whitelist/blacklist

re: the GWT Developer Plugin in Firefox and Chrome on Windows/Vista.

Within the plugin on Firefox I am able to include the public hostname
of my computer which is also the same as the hostname of my
application URL via the options dialog titled Security Restrictions.

The Chome version of the plugin does not enable the options. When I
connect to the same url as in Firefox, Chrome says it cannot connect
to my debugger.

Is there a control file or command line parameter that I can use to
whitelist a hostname/ipaddress ?

TIA,
