I just downloaded and installed the latest SSD updates (11/14/2007) in version 1.5.1.17 (beta). To my surprise, the immunization lists for Firefox (Cookies, Images, Installations, Popups) are all doubled. I use only the first; the others are unchecked. None of these lists was doubled before the latest definition updates were downloaded. The Opera Plugins immunization list is also duplicated: one is under the heading "Opera 7+"; the other is under "Opera 7+ 9.24.8876.0".

It appears that the Firefox Cookie immunizations are applied only once, not twice as doubling the lists might imply. This ought to be cleared up before the beta takes wing as a released version.
