NIS 2009 and Firefox Add-ons

Hello. I'm using NIS 2009 (16.8.0.41) and Firefox 3.5.8 on both Vista (32 bit) and Windows 7 (64 bit) computers. Starting around Feb 18, whenever either computer is restarted, all my extensions are automatically enabled even the ones that were previously disabled. Secondly, several of the extensions have red marks in front of them stating they are incompatible but they are not. Simply clicking on the 'check for update' button and re-starting Firefox gets rid of the incompatibility, but I still need to go through and re-disable the extensions I'm not currently using. This is time consuming and annoying. I've tried Firefox versions 3.5.7, 3.5.8, and 3.6 and have the same problem. Is anyone else experiencing this?

 

Thank-You
