Mine develop this error soon after "PR1.3" update. After uninstalling the "Nightly Beta 15" version of "Firefox" and installing the more recent "Firefox 13" from the "Nokia Store," I notice "2 Firefox Icons" on the dashboard. So I uninstalled, reinstalled and rebooted but no success. Then I decided to move one of the double Firefox icons to the Shortcut App (or quick lunch) Bar where the previous Nightly Firefox was (to the far right) and solved the double firefox icon issue. So now I've notice a bug with the shortcut app when you put in a icon wherever the blank shortcut icon is you get a blank or just a missing icon.The same is true even after you uninstall it. My blank/missing icon is missing in the same place as the "Nightly Firefox" version (to the far left) after uninstalling shortcut app. I'm a noob with few apps form the store by the way. Any help would be much appriciated.Thanks for time...
