We want to fix an issue in how Chrome generates the Accept-Language HTTP headers from user language preferences. As websites sometimes only accept languages without region (i.e. “en” vs “en-AU”), a user could receive websites in an unexpected language. We plan to add the base language in the correct position so that users receive webpages in their preferred language.
