actually aftes some research i have to say that it seems to be obsolete now as it is enough to set browser.newtab.url & browser.tabs.closeWindowWithLastTab your way...
but it will be missed ;)
i really love it, one of my 'must have' plugins, unfortunately "Not available for Firefox 13.0"
hopefully it will be updated soon
