You are quite right, Asyn, and I used to have NoScript but got muddled with it (I am rather old and doddery).
HOWEVER!!!
I thought to myself, why pay for all-in phone calls and not dive into the unknown free-of-charge occasionally? So I phoned M86 (01256 848 080) and a young man told me that Finjan has become "M86 Secure Web Gateway", which is being re-branded and updated to cope with today's threats and which will be available for us private users FREE within ("can't promise exactly", he said) a few weeks! AND, "it will be better than Finjan"
Breath-holding not recommended
