# Firefox Branding

Firefox has multiple different sets of "branding" that are used to hold channel-specific things such as:

- Logos and other iconography
- Product names (eg: "Mozilla Firefox", "Firefox Developer Edition")
- Channel-specific preferences (eg: `app.update.interval`)

Brandings are stored in the {searchfox}`branding subdirectory <browser/branding>` and map to builds as follows:

- `official` is used for Release and Beta builds
- `aurora` is used for Developer Edition builds
- `nightly` is used for Nightly and Try builds
- `unofficial` is used when no other branding is specified (eg: local developer builds)
