Version 3.5.2 installs a new default security certificate. Some browsers,
including Netscape and Mozilla, will not recognize the new certificate if
the original has never been replaced. If you are unable to log on to the
GTA Firewall after upgrading, delete the browser security certificate, then
exit and restart.
