It's a bit hacky, but I wrote a script which tries to guess the user's 
preferred browser, based on the current desktop environment.

function detectDesktop() {
	if [[ "$DISPLAY" = "" ]]; then
		return 1
	fi

	local LC_ALL=C
	local clients
	if ! clients=`xlsclients`; then
		# TODO: should we fall back to using ps?
		return 1
	fi

	if echo "$clients" | grep -qE '(gnome-panel|nautilus|metacity)'; then
		echo gnome
	elif echo "$clients" | grep -qE '(kicker|slicker|karamba|kwin)'; then
		echo kde
	else
		echo other
	fi
	return 1
}

desktop=`detectDesktop`
if [[ "$desktop" = "gnome" ]] && command -v gnome-open &>/dev/null; then
	gnome-open "$1"
elif [[ "$desktop" = "kde" ]]; then
	kfmclient exec "$1"
elif command -v firefox &>/dev/null; then
	firefox "$1"
elif command -v mozilla &>/dev/null; then
	mozilla "$1"
else
	exit 1
fi
