Trying to move different firefox profiles to different tags in awesomewm

rules.lua

		{
			rule = { class = "Firefox", instance = "Navigator" },
			properties = {
				tag = tags[rule_screen][2],
				floating = false, minimized = false 
			},
			callback = function(client)
				client:connect_signal("property::name", function (c)
					if string.find(c.name, "Pentadactyl") and not c.moved then
						awful.client.movetotag(tags[rule_screen][3], c)
						awful.client.setslave(c)
						c.moved = true
					end
				end)
			end
		},

				-- Ugly hack:
