Is Microsoft Bing Homepage & Search for Chrome safe?

Low risk

The extension reads the __utmz Google Analytics cookie from chrome.google.com to extract affiliate attribution data such as the traffic source, campaign name, and medium. This attribution value is encoded and sent as part of daily telemetry pings to go.microsoft.com. The behavior is used for affiliate and ad campaign tracking.
