Who’d have thought those tiny reminders of the site you’re browsing could bite your backside? Apparently Mozilla did, and with its latest nightly Firefox build it has expunged favicons from their eternal perch just left of the URL. The problem is that instead something friendly — like Google’s famous “g” — nefarious sites can use a padlock or similar image, making you think you’re on a secure SSL page. So, starting from mid-July you’ll see a generic globe for standard websites, green padlocks for SSL sites with validation, and gray padlocks for SSL sites without it. Take note that (so far) tabs will keep their favicons, so those of us with 43 sites open at the same time will still know where in the web we are.
