Firefox coolkey and RHEL aren't cooperating

This one has been a little hard to nail down in terms of logs but I have noticed that using common access cards and Firefox is now a gamble; sometimes it works and other times it hangs and I am forced to kill the process. In the meantime I'm using Chrome and patiently waiting for a newer version of Firefox to be released from Red Hat.

Has anyone else noticed this with cac cards? I feel like there might already be a bugzilla out there for this.
