NIS Confidential does not support Firefox 3.0.10

Just downloaded Firefox 3.0.10 for Mac today. Norton Confidential (part of NIS 4 for Mac) flashes a warning that it does not support that version, and that it cannot scan or protect my Internet activity. 

When will Symantec NIS 4 for Mac support Firefox 3.0.10? I really prefer it to Safari.
