Missing Labels in Firefox (Administration > Authentication)

Missing some field labels in Firefox but not in Chrome. See attached images for examples. Path to menu:

FishEye > Administration > Authentication > JIRA or Crowd Authentication > EDIT Screen

In my browser, this is the URL:
(http://localhost:8060/admin/crowdAuthEdit-default.do)

Thanks,
