I am sorely tempted to look for a new AV after this...
Thanks to Flood and Flood's Wife for the solution!!!
The "PR_CONNECT_RESET_ERROR" error took Firefox completely out of action for me after simply adding my new KIS activation code...
Then Drop box stopped working
Then Outlook Email stopped working
To say I've had a FRUSTRATING couple of days would be an understatement
Not helped by Apple Fanboys with their helpful "Buy a Mac" comments... ?
back up and running now though, thanks again F&FW :)
