Okay, my son’s machine is Win7 64Bit with AIS2014 latest version.

Ran SafeZone for :

Halifax Bank

Lloyds Bank

Nationwide

Santander.co.uk ( don’t have account there , but, entered online banking, ran their demo, visted all the links available.)

No problems at all.

Exit, run Firefox and his T’bird account , again, no issues of any kind , all works perectly.
