I searched Firefox Help topics and learned that the "Site Security Lock" icon has been replaced by a "Site Identity Button" indicated by the site's logo to the left of the site address. I have entered an assortment of sites, even reputable mail order sites, .gov sites, UPS, Craigslist, and almost all of them show, "This site does not supply identity information." I'm definitely not a computer wiz, so am I missing something here? Thank You!
