I have been playing this game since it started and out of the blue facebook started to report that I needed the latest version of a browser to continue to play the game. Despite updating my browser it still would not load and the help forums were not helpful neither were the developer. To cut a long story short what it turned out to be was WebGL in firefox and its relatively easy to sore out: 1. in the location bar of a new tab copy and paste in about:config 2. Accept the risk 3: In the search box copy and paste in webgl.force-enabled , double click on it to change the setting from false to true. 4: In the search box copy and paste layers.acceleration.force-enabled , double click on it to change setting from false to true. 5: Close firefox and log back into facebook. The game should now work with the new interface.
