I can't tell from your post whether you closed ff before the update
or after. I would always recommend closing then updating and then
re-opening, otherwise you could get some odd results. 

This update of FF brought along a bunch of nss package updates. I
believe that you need to reboot to get a stable system after these
updates.

I can't tell what you were trying to show with your grep output. All
it is showing is the grep (for firefox) itself.

By the way, it looks like you may be selectively updating your
system. The current kernel is 3.10.0-327.13.1.el7.x86_64. Your kernel
is from mid-february. There have been around 200 updates, including a
kernel, since then. Applying the FF update, with the other updates
that came in tow, without otherwise fully updating your system puts
it in an unsupported and potentially unstable state, so all bets are
off.

I would suggest fully updating your system, rebooting it, and then
trying the new FF again (without saved tabs).
