Xorg Freezes when using Firefox and the proprietary NVIDIA driver

Issue

• Screen freezes and hangs when running or scrolling in Firefox; though, the system can be accessed remotely.

• The following messages show in /var/log/Xorg.0.log when the X server starts:

  [   802.103] (**) NVIDIA(0): Enabling 2D acceleration
  [   802.103] (EE) NVIDIA(0): Failed to initialize the GLX module; please check in your X

• After updates or installing Red Hat Enterprise Linux 6.5 or later, using Firefox hangs the screen and Xorg must be restarted.
