It's called "Klar by Firefox" in Germany due to the naming conflict with Focus, the magazine. I haven't seen the update in the app store yet, though. Probably still rolling out.
Update: I can see the Update to "Focus by Firefox" in the App Store (the logo changed), but due to the rebranding in Germany I can no longer access the details page of that in the App Store. The German version, "Klar by Firefox", hasn't updated yet. Likely someone needs to build the rebranded version explicitly and just hasn't done so yet.
It kinda makes sense in German, probably meant to refer to something like "klarer Blick auf die Dinge". But yeah, it's still slightly odd. Then again, naming things is really hard :)
