Maybe the El Repo Nvidia driver has a problem with Firefox? I remember it was miserable installing the Nvidia driver a while ago... Looking at my log file, here's how I had installed the Nvidia driver from the El Repo repository: 1. I identified my kernel version: $ uname -r ==> 2.6.32-279.5.1.el6.x86_64 2. I identified my graphics card $ /sbin/lspci -nn | grep VGA ==>01:00.0 VGA compatible controller : NVIDIA Corporation GT216 [Quadro FX 880M] [10de:0a3c] (rev a2) 3. I identified the latest version of the graphics driver available: http://www.nvidia.com/object/linux-display-amd64-304.37-driver.html Note: I compared this latest version & support information with the latest available at El Repo in the next step. 4. I compared the Nvidia version with the latest available El Repo version: http://elrepo.org/tiki/Driver+Versions Note: I searched for "nvidia" to find the latest version to be "nvidia 295.40". 5. I enabled the El Repo repository: $ sudo rpm --import http://elrepo.org/RPM-GPG-KEY-elrepo.org $ sudo rpm -Uvh http://elrepo.org/elrepo-release-6-4.el6.elrepo.noarch.rpm 5. I installed the latest Nvidia driver from the El Repo repository: $ sudo yum --enablerepo elrepo install kmod-nvidia $ sudo yum --disablerepo=\* --enablerepo=elrepo install nvidia-x11-drv-32bit > if yes, are you using the driver package directly from NVIDIA (as > opposed to one of the RPM versions from, e.g., epel, or wherever...

So, you suggest I install the Nvidia drivers directly from Nvidia and not the Nvidia drivers from the El Repo repository? Note: I'm not sure I know how to do that.
