I've got Firefox in my apps folder but can't open it or drag it to my dock. The logo looks like our dvd player with an arrow pointing to the insert slot.
The firefox logo pops back to the apps logo list when I try to drag it down. I may have created a problem when I made a second Firefox and tried to drag it, too. On my screen it was called Firefox Alias. I dragged it to trash.
