enable/configure upstream search engine selector instead of defaulting to google

[An-anonymous-coder]

The default search engine in Trivalent is Google. Google is known to collect vast amounts of data. Each time the browser is opened, the new tab page loads Google's search engine by default. Changing the default search engine to something that doesn't collect data falls under Trivalent's "Changes that disable opt-in metrics and data collection, so long as they have no security implications". Alternatively, make the default page a blank tab or enable launching in incognito mode by default. Storing browser history should be opt-in anyways, so launching in incognito mode by default falls under Trivalent's "Changes that make secondary browser features opt-in instead of opt-out".

@An-anonymous-coder thanks for this

Upstream is putting together a search engine selector that runs on boot, our plan is to enable that once it's available so that there's no default search engine and the user has to select one at firstrun. We may customize it somewhat as well.

Storing browser history should be opt-in anyways, so launching in incognito mode by default falls under Trivalent's "Changes that make secondary browser features opt-in instead of opt-out".

Storing browser history is a primary feature, and is easy to disable in chrome://settings/security. Perhaps that could be more clear in the readme. "secondary" here means things like managing passwords, payment processing, etc
