Greg - MODIFIED?
back to MODIFIED - this is a 3.4 BZ, not a 3.5 one.
Verified in rhevm-3.4.3-1.2.el6ev.noarch (av12.2) with firefox-31.1.0-5.el6_5.x86_64. In FF31, Login page of Webadmin doesn't show message "This Browser version isn't optimal...". Automated tests also didn't show any regression in UI functionality with FF31.
