I'm using Spybot S&D 1.5.2 on Windows Vista Ultimate. The immunization feature does not recognize Firefox, it doesn't even show up in the list. Internet Explorer shows up just fine. I've uninstalled and reinstalled Spybot, deleted the program data folders for it and can't get the problem solved. Does anybody have any suggestions? Also, I ran a tool called Browser CI I found a link to in another post, and Firefox does not show up in the list on the left side where all the IE entries are.
