Compatibility/Google Search Tier 1

Google currently sends Firefox for Android to a "Tier 2" search experience, while sending Chrome Mobile a "Tier 1" search experience.

The Web Compatibility team has a goal to get Firefox for Android users on Tier 1, pending analysis of known issues, and Gecko fixes where required. We can achieve this via user agent spoofing, but we would prefer to work with official Google channels.
