Is TabMetrics safe?

Medium risk

TabMetrics sends new-tab telemetry and search input to tracking and search services from its replacement new-tab page.

On each new-tab open, TabMetrics posts a stored extension profile plus user agent, browser/OS details, screen resolution, DPI scaling, and viewport values. As a user types in the new-tab search box, the query text is fetched from suggest.tab-metrics.com with the stored GID, and submitted searches are sent to icftink.com with stored tracking fields.

Where it sends data
