I just tested manually installing an outdate language pack for es-ES https://addons.mozilla.org/firefox/addon/espa%C3%B1ol-espa%C3%B1a-language-pac/versions/ Indeed, searching for updates doesn't find the most recent version. Why? For users affected: reinstalling the language from this page and restarting should solve the issue https://addons.mozilla.org/firefox/language-tools/
