Loading issue with your Mafia Wars game.

We monitor our game performance very closely and make every effort to let you know in advance when your connectivity may be hampered due to issues on our end. Remember that any time you experience a loading issue, a good rule of thumb is to try refreshing the page once or twice. If refreshing does not result in your game loading properly, try the following troubleshooting measures.
 

Use Google Chrome or Mozilla Firefox as your default browser

We suggest that you use Google Chrome or Mozilla Firefox for the best game play experience. We also recommend that you always make sure that you are using the latest version of your browser. These are the last versions of the different browsers that support Zynga games: 

*Google Chrome
*Firefox
Having your browser updated can help improve your game play experience. To check which browser version you are using, go to the Help menu of your browser window and select About. To upgrade to the latest version, click any of the links above.

There are several documented issues surrounding Internet Explorer (IE) and Flash content. We do not recommend IE as your browser.

For higher performance, we recommend you to play via mafiawars.com .
