Unfortunately, this addon (and the one suggested by Pietr) currently only works on Firefox; I use Seamonkey. It's my understanding that almost everything that can be done on FF can be transferred to SM with a relatively simple due diligence:

... tho' this is for the website itself, not add-ons. It would be great if you could tweak this for SM users (and, of course, if the fine coder volunteers for FF & SM would build this functionality into the browser, as the default or as a preference).
