Bug 376919 adds a pref to disable microsummary updates which causes in-use live titles to become frozen in time. We should flip those titles back to their static forms when microsummaries are disabled and back to live titles when re-enabled. Per bug 376919 comment 2, waiting for places to be turned on by default will make this significantly easier to do.
