An alternative way to John10cz's way is after editing the install.rdf file, place the edited install.rdf file back into the .jar to overwrite the old and change the extension to .xpi. Firefox should recognize it now and will prompt for installation when opened. Hope this helps some who still want to use the theme in 3.6.
