I believe that the default driver for nvidia cards is nv, not nvidia, due to licence issues with the proprietary nvidia driver. You may want to ask about this on the community forums (for example, at http://www.ubuntu.com/community/forums/document_view).

Also, this isn't a problem with Firefox - you might want to file a bug on nv about the slowness with firefox.
