I tried to download Firefox today. The application folder had disappeared from the finder and when I finally located it, and tried to follow the instructions to drag the icon from the download box to the application and then to the desktop, a box appeared and said that it was corrupted? Apparently I need an older version of firefox? Can anyone give advice? My dumb b ank has gotten rid of safari and I don't have explorer on this laptop.
