Hi, I was wondering if someone could help me, I'm not the best with computers! A few weeks ago I started experiencing some problems with my safari as it kept closing on random pages on facebook and on amazon. Then suddenly a few days ago it decided that it would simply close entirely as soon as I logged onto facebook or entered amazon, and now it is doing this with more and more websites. So after a bit of a search on the net I was told to delete all of the safari directories, caches etc, so there was nothing left on my computer of safari, and then to reinstall. Problem is it won't let me reinstall safari off the apple site, it keeps saying the system can't download it. So I already had firefox installed, and the same problem happens on that too. So after installing a few security checkers I'm still not sure what to do to fix the problem, and whether I should get safari back and how..and suggestions? would be very very grateful!
