NIS2009 & Firefox 3.0.9 problems...

I have a Norton Internet Security 2009 and Firefox 3.0.9 installed.

 

The problem, is that I can see a link scanner verifications in IE8, but not in my Firefox 3.0.9!

 

I've checked my Firefox's add-ons, and there's only Norton IPS and Norton Toolbar installed.

 

Is there something missing there? Maybe it's my brother's activity (he doesn't likes such add-ons)? How to take everything back on?

 

Also - I've had such add-ons, like from a Real Player (to download *.flv videos quickly) and something (one thing) more (maybe it was Java... don't know/remember).

 

Thank you for your support!
