I have an Imac 27in late 2009 build OSX 10.8.2 with Safari 6.0.2 It started a few days ago failing to allow me on my internet banking site, then I tried my medical web site where it refused to recognize my password and would not let me change it. Later it would not even let me use my password to get on the apple site, What is going on? I thought it was bad enough that it was impossible to play a video more than a minute or so but this was impossible to work with. For the last 2 days I have spent full time trying to fix the problems using suggestions in these discussion groups. I finally installed Firefox which (at least in the past couple of hours) seemed to solve all the problems. I am able to play videos, have been able to get on the web sites although I did have to change my passwords. I imagine that was because I had made so many attempts, the sites were frozen and had to be restarted. Was my trouble due to Safari bugs or something an old man did?
