@MonstraGwe have not added Norwegian to the list of supported languages because it did not appear to meet our quality bar. We might revisit this decision after we collect more data about its quality. When you used it, were the translations correct?
You can access all models, even experimental ones, by using Firefox Nightly.
I don't remember how correct they were, but I think I will be okay with even a sub-par translation, as it is the only reason I keep chrome installed on my system.
I'm using firefox developer edition, can I enable them it trough a flag or something?
