Is New Tab Tools safe?

Clean risk

New Tab Tools captures page thumbnails for saved tile URLs and stores them locally with the page URL.

New Tab Tools watches completed page loads and, when the URL is one of its saved new-tab tile URLs, captures the visible page into a thumbnail image. It skips incognito tabs and stores the thumbnail blob together with the page URL in the extension's local IndexedDB storage.

Shared hosts - 1 hostname

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
