Apparently the newest version of FF does not support Top Sites. Top Sites was a FF feature that allowed you a homepage with links to the top dozen or so sites you use. It had mini versions of the page for each site. I used it all day long to check my bank/credit cards, CNN, Ebay, Amazon etc. Now I saw an add on called Fox tab. It returned the Top Site option that appeared when I right clicked on a page. I set up a few Top Sites this way but when I hit the + at the top to bring up my Top Sites home page with the icons, a red background version comes up. This version does not function. It appeared right after the last upgrade in Feb.
