I'm new to Firefox; just switched over from Flock. I'm loving this browser so far, but there's one thing that's bugging me. In Flock, when you go to a page that has clickable images, the images have a black border around them. It helps to differenciate the clickable images from any non-clickable ones on the same page. But on Firefox, those borders aren't there; all images posted on the page look the same, with no way to tell at a glance which ones are clickable. That was a feature I really really liked, and made use of every day. Is there any way to set Firefox so it displays the borders the way Flock does?
