Issue with NIS 2010 (17.5.0.127) - Firefox 3.6.2 - Norton IPS 2.0 deactivated

Hello,

I just made an upgrade to Firefox 3.6.2. When the installation of FF 3.6.2 has finished it shows a message that Norton IPS 2.0 is not compatible and has been deactivated.

 

What can I do to reactivate Norton IPS 2.0?

 

I'm running Windows XP SP3 (up-to-date) with NIS 2010 (version 17.5.0.127).

Hope you can help me with this issue.

 

Thank you very much!

 

Edit: I forgot to mention: I already ran LiveUpdate several times and restarted my computer but nothing changed.
