Agreed Grubby.
I realise Firefox isn't the be all and end all of security, anyone who has a clue know's that's not the case but we're often talking about people without any kind of clue. I'm not being derogatory or eliteist, most people just don't have the time to learn and want to use the net as they use a household appliance. Anyway, in practice I've found that pushing friends and relatives over to FF works 99% of the time which is a good enough result to recommend it.
Also, isn't it ironic that the majority of users of Mozilla are the people who can use IE quite safely with the reverse being true for IE. Funny old world
