We need to add 'brx' to browser/locales/all-locales on mozilla-central.

PS: to be clear to the localization team, this bug is handled by Mozilla staff.

Turns out we can't add a locale without having search settings. That's surprising, given that the previous system would fall back to en-US settings.

@Mark
Is this expected?

I think what's happening here, is that the engine configuration is actually wrong and trying to ship Bing, Amazon and eBay on these new locales when it shouldn't be. My suspicion is that it could be something to do with the new default configuration added in bug 1575554 - however that should only be being used when there is no region specified.

I've filed bug 1585257 and will try and figure it out today or tomorrow.

As I just said in bug 1585257, I've now realised this isn't the new modern configuration.

This is the legacy system that is falling back to the "default" settings, but that's not what the tests are expecting, so they're calling it out.

So probably the right thing to do for now is to add the locales to list.json with Google/DDG/Wikipedia since that's what the modern config will be shipping.
