never said it had no security holes. as I said, 'if you think firefox will protect you from popup/popunder infection don't be so sure'. -  I'm not sure where you read I thought it was secure?

as to "or that this is the prevailing impression" I think that comes from the repeated advice that you use FF to avoid infections. do a search and you'll find plenty saying that.

personally I think the only secure computer is switched off, dismantled and then buried in a peat bog.
