hey there i had a similar problem at first, tried to exit with just a red error message "check internet connection" at the end of the counter.
i've written a ticket to the support team and explained, im using up to date firefox x64, no plugins, got vcredist, .net, java and flash player up to date
answer:
"Hello,
please make sure you have WebGL enabled.
For Chrome:
To enable WebGL support,
all you have to do is download the latest Chrome Beta from the Google Play
store.
Once installed, enter “chrome://flags/” (minus the quotes) into the URL bar,
scroll down to ‘Enable WebGL’ and relaunch the browser.
For Firefox:
First of all, be careful as these instructions will require you to tweak
Firefox configuration.
Now type about:config in address bar and in the search box type webgl. To
enable WebGL, set webgl.force-enabled to true.
If using Windows, you can follow these additional steps.
Enable Layers Acceleration, by setting layers.acceleration.force-enabled to
true (can be enabled in Linux as well but there can be frequent crashes and
glitches)
Set gfx.direct2d.force-enabled to true.
Just restart Firefox and try the game.
