FF 11 Comp Model HP 7700 Win XP SP3 and all updates MS Security Essentials w MS Firewall SPB v. 4.6 batabase 4/16/2012 DSL Verizon connection ============================== I've been using Firefox almost since its inception, and SWB always tells me it can't detect a FF profile. My profile is in the standard place. This also applies to all previous versions I've used on several other comps, all with different security programs. I've let it slide because of FF's own security options. Your KB directed me to remove a FF profile file "registry.dat," but no such file exists. My security add-ons in FF are: AdBlockPlus, WOT and TrackMeNot. I have also checked the Options box "Tell websites not to track me." I have already checked this out, but all my files are always visible: http://www.wilderssecurity.com/showthread.php?t=317923 SWB does work properly on IE, but I rarely use that program.
