> Google specifically serves a worse version of Search on Firefox for Mobile.

I don't think Google owning Chrome is really a factor here, but just a raw traffic question where FF Mobile has basically zero uptake. The experience they serve on FF Mobile is just the "we arent subscribed to validating that all of our shiniest JS works with this version of this browser".

The extension spoofs the user agent and arbitrary obscure features that only trigger on specific queries may be broken.

Google does do the effort of validating on other browsers where the traffic threshold is higher, including Firefox on Desktop. If they didn't own Chrome nor Firefox they still wouldn't really have incentive to spend more time supporting the tiny fraction of users.
