It's currently also true on Android, because Gecko doesn't yet provide a WebView style embeddable component, so Firefox Focus uses the default Android WebView instead.

There's a bug tracking work to migrate to Gecko though: https://github.com/mozilla-mobile/focus-android/issues/13 (see also the linked https://bugzilla.mozilla.org/show_bug.cgi?id=1322573)
