Inside the browser language pack is enabled, but I still have it with english locale.
Furthermore, Firefox Developer Edition is being shared with specific language on Mozilla websites, earlier when I was using it from the AUR it was downloading a package with specific language not like Firefox Standard with separated locale file.
Any ideas? I don't want go back to the AUR because it is more convenient for me to get it from the repositories because it's being constantly updated.
