Not logging web activity, but logs searches

I just installed registered for NOF and installed NSM. Everything went smoothly.  When I check web activity it shows nothing.  I didn't think it was doing anything at all, but searches are now showing up in the Search tab, so I know something's working.

 

What do I need to do to be able to see web activity?

 

In case it's hepful:

Mac OSX 10.6.8

Firefox, Chrome, and Safari are all installed. 

Firefox is the browser I've been using. 

The Firefox extension Norton Safety Minder for FIrefox 2.1.10r113 is running.

 

Thanks!
