Flash player crashes with latest Firefox update 47.

I upgraded last week to Firefox 47 and immediately could not load any games from Facebook. My adobe crashes as soon as the games start to load, I have contacted Firefox support, Facebook support, and every game support that I play but not getting anywhere. I can play them in Chrome and IE and I have tried every step that all of the support people have sent me. Nothing works and I miss using Firefox. I do not care for Chrome but it is the only browser I am able to play the games. I am using a HP laptop with windows 8.1, 64 bit with almost 6 gigabytes free. I have cleared Adobe cache, Firefox cache, etc. Please tell me how I can make this stop so I can use Firefox again.
