Bug 1500103 - Only test return_button_adv and exception_button for new cert error pages. r=nhnt11 exception_button can technically be clicked on the old error pages, too, but conditionally checking for the cert exception window to pop up is a bit overkill for this temporary workaround. Ideally we would remove this pref soon anyway. Differential Revision: https://phabricator.services.mozilla.com/D9243
