I am continuing to enjoy Spywareblaster as I have for several years. Just out of curiosity, I noticed that I can now clear my Site Preferences in Firefoxwithout SWB partially disabling protection. This occurred approximately 2 weeks ago (before the SWB 4.6 upgrade and also prior to either of the 2 recent Firefox upgrades). How did this get fixed? I am running Win XP sp3 along with Kaspersky Internet Security 2012. Thanks again, Howard T.
