Mozilla Thunderbird is now available in three new beta languages – Armenian, Asturian and Croation. We’ve released these as beta languages – they are relatively new languages and have received some testing, however although the core is based on the same version as the released Thunderbird, there may still be some translation issues on the interface.
If you want to give one of these a try, then you can obtain them from the beta languages section on our download page.
If you find an issue with the translation, please report it under the respective localisation’s component here.
