Hi, Most of the people answering questions here are fellow users volunteering their time (like me), not Mozilla employees or developers. If you'd like to request support for additional language in the Firefox translation feature, please consider voting on the following idea or starting a new one if you don't see the language that you desire listed on the [https://connect.mozilla.org/ Mozilla Connect] platform. * Arabic : https://connect.mozilla.org/t5/ideas/include-arabic-translation/idi-p/40938 * Norwegian: https://connect.mozilla.org/t5/ideas/firefox-translations-support-norwegian/idi-p/44284 * Thai: https://connect.mozilla.org/t5/ideas/support-translating-to-thai/idi-p/89654
