Could someone explain (or point me to some documentation explaining) how to change the helper applications used by Epiphany and Firefox browsers. I'd like to use Real Player instead of Totem for Real Audio links but I can't find where to configure this. (Actually what I'd really like is a right-click menu like in Nautilus giving a choice of Real Player, Totem, mplayer etc., although I suspect this isn't possible!) Many thanks, Ben Mulvihill
