Last I checked, the extension was "unsigned" - i.e. Eluvatar hasn't gone through all the rigmarole of getting Firefox to consider it a "trusted" extension. That means it's nigh-impossible to use the Firefox version of NS++ (and I'm not sure if it even is possible at all).
As a Firefox user, I would recommend installing the Greasemonkey extension and then adding LibreNS++, which is a separate but similar addition to the game.
