It's a landing page. Why does it need the loading animation? Even though it takes less then 2 seconds, it instantly put me off.
Hi .. It is mainly there for slow connections and mobile devices. Will look at potentially not displaying it for a few seconds so fast loads will not see it.
Sorry to see that you got a blank page .. did it remain that way after a refresh? I have tried the page in many different browsers and never received a blank white page. I wonder if it could be related to the GNU browser you are using.
Sorry for the negative comment :). I think it's due to the addons IceCat ships with.
