Norton IPS 2.0 no longer works after updating Firefox to 4.0

Why hasn't Norton kept up with the release of this new browser version, the release was 4-5 months ago and you guys still don't have an update for the IPS 2.0 out yet?

 

Lets hustle up a little please. Now there is a function I paid for I cannot use, rather irritating.
