I am writing this because I received absolutely no help from Zynga when both FarmVille and CityVille crashed my Flash plug-in each time I tried to load the game for almost a fortnight. Having played FarmVille for almost two years, the response Zynga sent, which was to copy and paste an elementary list of system requirements, made no sense whatsoever and was unhelpful in the extreme.
The fact that the many advertisements linked now to FarmVille and CityVille ALWAYS loaded easily and only the game itself was unable to load was a clue that the problem lay within the actual games and new options that pertained to the Flash plug-in.
Note here that I am not technically advanced where the internet is concerned. I cannot write software or code and basically can perform only the most basic tasks on my laptop. I had hoped for some expert advice, therefore, but it was not forthcoming.
The Adobe site was my next stop on the internet highway, but 'support' is offered only to paying customers. I then tried to research the problem myself. What I discovered was that one needed to be able to access the Flash Settings Panel. Alas, whenever I attempted to do so, IT crashed instantly as well! I therefore could not perform any actions whatsoever to change the settings.
My research led me to some reports that camera and microphone access sometimes led to Flash plug-in crashes. If I had possessed the ability to go into my Adobe Flash settings, I could have made certain that this access were denied but I could not do that.
Meanwhile, I could not play either FarmVille or CityVille on my own laptop. Note here that I had enabled Zynga to save data for FarmVille and CityVille on my laptop long ago. The worst part of the problem was that I could not send any Crash Report to Firefox or Adobe when the Flash plug-in crashed. Each time it crashed and I attempted to do so, 'submission failed'.
I uninstalled Flash in all of its manifestations and then reinstalled it, but in vain... The problem continued. Oddly enough, I still was able to play Fantasy Kingdoms and Gourmet Ranch on Facebook as well as loading streaming video on other sites. The problem therefore was peculiar to Zynga games.
There is one aspect of FarmVille and CityVille that has changed radically since the games first were released. The amount of data used is tremendous and if you do not allow Zynga to store data on your computer, you may not be able to load these games easily or handily. If the games do not load quickly and 'hang' for any length of time, you need to adjust your Flash settings to allow storage of data. Quite a lot of data actually...
I was able to solve the problem with the two games only after I finally was able to load the Settings Panel without a crash. Firefox has updated itself in the past week so perhaps there was a fix involved in that update. (I could not load the games on Chrome or IE either, however, so it may have required a Flash update of some kind. I always install all the latest updates in any case.)
Perhaps this is a pointless post because I don't have the technical knowledge required to assist any one else, but I wanted people who have experienced the same issue to know they aren't alone and that allowing Zynga the capacity to store a lot of data on your computer/desktop may be part of the solution. Clearing my Cache did nothing but clearing my Cookies may have helped as well.
