I now have Firefox and Thunderbird on both my MACs and my
PC. Firefox is the browser and
Thunderbird is the email program. They
are all working, they installed easily and they are small programs by
contemporary standards. Both programs picked
up my old lists and settings perfectly.
I have kept the MACs because they are very stable and didn’t get viruses even before Mozilla.
I have used Mozilla for two months. It seems to protect the PC from viruses.
