After reading that Knowledgebase article, my understanding is that SiteAdvisor 2.6 (I'm assuming this means the IE version) ends next December but the version for Firefox that ends at that time is 2.8. My question is did 2.8 come as a package deal like 2.9 (i.e. with the IE and FF versions as well as the Service that some have mentioned)? What is the purpose of the Service? When I had 2.8 installed I don't remember seeing anything that related to the Search Bar but I did see it in version 2.9 (although I opted not to have it installed).
