# SYNC_ENGINE_UNAVAILABLE

`SYNC_ENGINE_UNAVAILABLE` [(source)](https://github.com/mozilla-mobile/android-components/blob/master/components/feature/syncedtabs/src/main/java/mozilla/components/feature/syncedtabs/view/SyncedTabsView.kt#L77)

The engine for syncing tabs is unavailable. This is mostly due to a user turning off the feature on the
Firefox Sync account.
