I recently sent a question to you guys about my problem with 48.0.2 and this is the answer I received..... "Firefox 48 crashes at startup if websense is installed. Right now, they aren't sure how to fix it. The hotfix was deployed to people using Firefox 47 and lower (down to 40) to detect if websense is installed, and if so, not update Firefox yet. I don't see how it would affect game rendering. It's probably not the cause, considering disabling it doesn't fix the problem. :) What games are you having the problem with? If you can provide the address, we can check what the cause might be. If it's on Facebook, try the solutions at Fix problems with Facebook games, chat and more." Maybe a photo will help..
