Environment: - German browser - or Language is set to German i.e. Accept-Language: de-de i.e. http://browserspy.dk/language.php shows "Language de-DE, Accepted-Languages de-de, ..." Reproduction: 1. Go to preferences | Content | Languages | Choose... and add "German/Germany [de-de]", and move it to the top of the list. 2. Go to https://www.mozilla.org/Security Actual result: - You get redirected to https://www.mozilla.org/de/Security - This does not exist, so gives 404 "Page not found". Expected result: - You get https://www.mozilla.org/Security with the English content Generally: - Whenever there is no corresponding translated version, *or* the translated version is outdated, then the redirect does not happen. - or Subpages do not redirect, only the main https://www.mozilla.org redirects to a localized version. This bug does not only affect this particular page, but any such pages. Importance: Major - loss of an important function
Ah, http://www.mozilla.org/security/ works So apparently the redirect happens only for pages that are 404 anyway. That's still confusing and the redirect shouldn't happen.
