I am trying to install firefox and the only version available is 4.o and my computer will not allow me. 2nd my norton antivirus would not protect my older version, the message said I needed a newer version for norton to add its tool bar. I tried upgrading, no luck. I uninstalled and now 4.0 is the only version that is available.
