Q: Is Adblock Plus safe?

Adblock Plus is low risk. The rating reflects signals from our analysis that have not yet been published as detailed findings.

Low risk

Adblock Plus injects a persistent installation UUID and account metadata into the DOM of every web page, readable by any page script.

On each page load, Adblock Plus writes a JSON payload to a dataset attribute and a hidden DOM element. The payload includes a stable cross-site tracking identifier (installation UUID generated at install time), premium account ID, lifetime ad block count, install date, and experiment flags. Any script running on the page can read this data without any authentication or permission check.

Part of this rating comes from analysis signals we haven't published as detailed findings yet.

Shared hosts - 4 hostnames

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.
