O.K. so here is the deal with Firefox. If you can't play and get a message saying your browser is not supported. Here is what you need to do. 1st go into your computers control panel and click uninstall program. 2nd delete every Firefox app. that you have. 3rd using a different browser other than Firefox, search for (Firefox 51.0.1) download and download it. Do not install anything newer than 51.0.1 When it asks if you want to install standard or custom, choose custom. Do not check auto update or the maintenance that is offered. If you do, you will find yourself in the same situation. Firefox versions after 51.0.1 are no longer compatible with the Java offered by Fly or die. If that doesn't work take your P/C and toss it out the window.
