Firefox 10 is currently a Beta version and Norton doesn't support pre-release Beta versions. See this regarding Firefox 9.0.
Basically, just run Norton Live Update as often as you need to - some users have said it took 3 or 4 tries for the Live Update to retrieve the updated Norton extensions for Firefox.
