I bought kis2013 over the holidays to install once the KIS2012 license expired.
once activating the license today and installing the 2013 version Firefox stop connecting to the internet,
IE10 did for a while until I decided to reboot then none of them worked.
Yet Thunderbird was working fine.
In order to get firefox to connect to the internet I had to "disable the protection"
even disabling all modules but the main "protection" still would not work.
reboot, remove, install, reboot, remove, install again, nothing work.
during installation of kis2013, I had firefox open and working... but
as soon as kis2013 installation finish firefox stopped working, with message
"The connection to the server was reset while the page was loading"
Only on one machine, my other two (win7, win8) have no problems
I had to remove KIS2013 and re-install KIS2012 to get Firefox to connect.
