I am sorry to hear that the functionality of the webpage is preventing you from playing your game. It seems like they have documented how to enable Fash: [http://zyngablog.typepad.com/farmville_2/2017/08/browser-support-firefox-.html]. However, your webgl renderer is also not working from the looks of your profile info. Can you please try to disable hardware acceleration and check if there is an available update? *[[Upgrade your graphics drivers to use hardware acceleration and WebGL]] *[[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]]
