New comment by eoli3n on void-packages repository https://github.com/void-linux/void-packages/issues/27255#issuecomment-748595035 Comment: From https://firefox-source-docs.mozilla.org/intl/locale.html#requested-locales > After the sanitization, the value will be stored in a pref intl.locale.requested. It seems that PKGBUILD does this as said before. We can also read: > If the developer wants to programmatically request the app to follow OS locales, they can assign null to requestedLocales.
