at the moment but as I recall there is something different about updating SiteAdvisor in Firefox. Its and add-on but not handled like updates are done in Firefox.
If it was me I would uninstall the add-on and start fresh with a new Firefox install from here.
Follow the instructions to a "T"... think that is the way I updated mine.
Hope this helps... good luck!

This utility suddenly stopped working in FireFox. Removed and reloaded, but still no joy. Works OK in MSIE 7.
I get the offer to upgrade, but when I click on "No Thanks", that screen reappears.
