Another computer in my network was using internet explorer and it has crashed. Would love to set it up with mozilla, however, can't get on the internet from the computer running the windows 7 that previously ran the internet explorer. Not sure if I can copy file to CD (or how) or do a free download to the windows 8 system possibly to a CD/flash drive and then install to the windows 7 system. Again, the computer I plan to use for the install has windows 8 & mozilla so I'm a little afraid of downloading a version on the same computer and messing up my windows 8 browser. Any suggestions?
