Er, sorry, we do have a pref.  So either go to about:config and
create a new boolean pref with the name
"mozilla.widget.disable-native-theme" and value true (and then
restart Firefox), or add (while Firefox is not running) the line:

user_pref("mozilla.widget.disable-native-theme", true);

to the prefs.js in your profile
