When the original BF4 beta drivers came out they permanently destroyed Firefox. It's something to do with Flash, I can't quite put my finger on it but sadly after 10 years I have had to abandon Firefox. I tried everything including a clean install of my OS and all software on a brand new SSD, as soon as Firefox was installed and updated the same problems were back again. Whatever destroyed Firefox did it the last week of October 2013. I emailed Firefox support with the situation and never heard back. Frank if I knew this was a problem outside the game I would have asked if you use FF. Glad you guys got it sorted, bummer to lose such an awesome browser though. I'm still trying to figure out what browser to replace it with. I don't want to expose myself to Google Chrome and it's intrusive oversight, I'm thinking maybe Dolphin.
