Why can't I play Zynga games on Firefox, but I can on Internet Explorer?


Ever since updating Firefox the other day to the 5.0.1 version, I can no longer play Zynga games on my Facebook (but can play other games from other companies); however, I can play them on Internet Explorer. How do I fix this? I've invested a lot of time and money into my PetVille game and my Treasure Island game, and I would really hate to have to switch over to IE to have to play them. Would downloading an earlier version of Firefox help with the issue, and if so, where can I download it from? Or, is there some extension or add-on from Firefox that I download that would fix the issue, and if so, where can I download it from?

When I updated my Adobe Flash Player tonight to its latest version, my Zynga games loaded on Firefox and I haven't had any issues so far!
