You know that Firefox beta7 has been released for a long time. Some of my friends have been using it with great satisfaction, and they suggested me to have a try. So I attempt to install it on my laptop which is with Windows 8 installed as the operating system. After the downloading of Firefox, it is of fast speed with some compatible plugins. But when I set the browser and its font, I found that the pull-down menu displayed abnormally. I do not know why. Does playing games have negative impact on it?
Thanks a lot!
