I'm going to wait and see what the IRC logs say before deciding if this needs any further action.
ETA: oh and it's precisely because of dodgey sites that I don't use that auto reload setting.
And no, it doesn't rewrite any browser sttings.
Devious, treacherous, murderous, neanderthal, sub-human of the West.
