Error Message - Norton Confidential - New Version of Firefox

Hi,

 

New to the community and hope I'm following protocol.

 

I just updated Firefox to version 15.0.1 and I now get a message that says "Norton Confidential cannot protect you while you use this version of Firefox. Phishing Protection requires Firefox 1.5 or later."

 

Any idea what I can do to fix this issue?

 

I'm running Mac OS X - 10.7.4.

 

Thanks for any help you can provide.
