Well that is weird..
I just tried to duplicate the situation with firefox and the shop site...
and If I go directly into the shop it's no problem now..

(Now the big prob I did find the 1st time around... and I haven't duplicated it since (it would mean ordering a second board ...which I really would love to do ) was the last steps in the ordering process..firefox didn't want to show the last steps in ordering..hence I ended up having to use chrome.)

The https://my.neo900.org/ http://neo900.org/pre-orders-and-vouchers links in the emails works fine..

But now ..If I use the other links provided in the emails
"order history" https://{history_url}/
"my account" https://{my_account_url}/
"guest tracking" https://{guest_tracking_url}/?id_order={order_name}
show up thus..
they aren't working properly. At least in my firefox anyway.

Anyway ..can't expect total seamless compatibility with every browser on the planet..
didn't confuse me or put me out in any way ..
I figured if I couldn't accomplish it in firefox another browser suffice.
I'm just happy to have been able to order.
