I wanted to switch from netscape to Mozilla firefox. When I downloaded the software I encountered email problems. I could read my emails, but i could not save, copy, reply. The entire menu on the left side of my emails disappeared. Netscape people said Firefox was incompatible. They deleted Firefox and I was back to normal. Later, I tried again to download firefox and have the same result. Now i seem to be unable to completely delete Firefox and cannot respond to my emails.
