Is Site Site Blocker: Stay focused & Block websites safe?

Low risk

Site Site Blocker exposes a short extension identifier in the page DOM on every site it runs on.

The extension runs a content script on all sites and frames, then appends a DOM element whose id includes the first five characters of its Chrome extension ID. Page scripts can read that marker to detect that this extension is installed, but the confirmed claim does not show user data being sent to a remote recipient.

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