I had also this problem with the Italian language pack.
I tried these ways :
1) purge of firefox-locale-it deb package (it is from Ubuntu repo and the version is 50.0.2+build2-0+8+build39) then install of Italian language pack directly from Firefox site > no solution, not working
2) install of firefox-l10n-it deb package (it is from Ubuntu repo and the version is 51.0-1+9+build29) and no language pack from Firefox site > no solution, not working
3) install of firefox-l10n-it deb package (it is from Ubuntu repo and the version is 51.0-1+9+build29) and Italian language pack from Firefox site > no solution, not working
4) install of firefox-l10n-it deb package (it is from Ubuntu repo and the version is 51.0-1+9+build29) and Italian language pack from Firefox site then :
- in address bar type about:config
- search general.useragent.locale
- change the value of the string from en-US with it-IT
- restart Firefox
> this is the solution, it is working !
