Heads up: SUMO redirects based on client locale may be 404 for non-en-US users

The SUMO site was recently migrated to a new CRM system called Lithium.
IIUC, the new Lithium SUMO site does not yet support redirects to
localized pages. (This is bug 1324426.)
If your Firefox feature includes a "Learn more" link to a SUMO permalink
(like https://support.mozilla.org/kb/whatever), the redirect might be
broken for non-en-US users. I ran into this problem in Firefox 52 with
both the Windows XP EOL "Learn more" link and the NPAPI EOL "Learn more"
link in about:plugins (bug 1346230).
