Now that version 28 left beta, and waiting almost 2 years for a stable release, I was looking forward to finally be able to use Firefox in Metro interface. However, I can't find the option to relaunch in Windows 8 touch mode in the Firefox menu that I had seen when I briefly tried the beta. Neither the icon on the start screen looks like other Modern UI apps, but is the default Dekstop icon on a tile. I had uninstalled the beta once I was done looking at it a while back and now updated my stable release, but can't find it. What have I done wrong?
