Hi, I'm wondering how to change my browser language in FF70 Nightly?

As the title says, I'm having trouble changing the browser language in FF70 Nightly. I can see the option to change the language for displaying pages but I no longer see the option to change the language for menus, messages, alerts, etc.

The only option shown doesn't change menus, messages, etc. It also seems like the browser language does not change if I change my OS language.

Is there or will there be any way to change browser language in FF70?

It is disabled in Nightly builds and you can toggle the intl.multilingual.enabled pref yourself .

You can install a language pack manually (extensions.langpacks.signatures.required = false).

You probably need to close and restart Firefox. You can verify the result on the "Help -> Troubleshooting Information" (about:support) page.

I see, thanks.

Do you know if FF70 will eventually be rolled out to the stable channel like this, or is this just how language preferences are set up for all Nightly builds?

The AMO website doesn't support the Nightly build update channel for language packs as you can read in the comments on the linked DXR page, so it is no use having this section enabled because nothing will work. Once 70 becomes the release version then AMO will support language packs just like it does for the current Firefox 68 release, but then Nightly builds (72) will still be unsupported. It is more difficult because language packs need to be signed by default. It took some fiddling for me to get this working. Nightly builds are meant for testers and not for normal users.
