HTML5/WebGL: Game Not loading or frequent crashes

[melian1]

Hangs up on the black screen (the progress box not filled in at all), and the error insert box finally appears. Done all the usual, reboot, run memcache, different browsers etc. Farm ID: 1793409352
On Chrome:

On Firefox, the progress box gets about 9/10th of the way filled, but it never goes any further, but the insert error box doesn’t appear. The Firefox info:
