Is OpenTabs: Save trees by surfing the web safe?

Low risk

OpenTabs sends new-tab search terms and its click_id cookie to p.opentabs.org.

When you search from the OpenTabs new-tab page, the extension reads its click_id cookie and sends it with the search text to p.opentabs.org before opening the search. Its sponsored shortcuts also create a persistent local UID and send that UID with a country code to tiles.takernd.com to fetch sponsored tiles.

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.

Where it sends data
