Firefox gives you control over different types of language settings:
- Display language — the language used for Firefox’s menus, settings, and interface
- Website translation — automatic or optional translation prompts for websites in other languages
- Preferred content languages — used to choose the language of multilingual websites (when available)
These are managed in separate parts of Firefox Settings, and they can be used together or independently.

- Verify you’re not using a VPN that would be chaging your region
