HTML game inspection
Inspect page content, scripts, and embedded frames for game signals—even on an allowed domain. Pages that merely discuss games are not blocked by a single keyword.
Scans stay on this device. Changing pages are rescanned. Detection uses game engines, play controls, scoreboards, and known embeds; it can miss disguised games. Reload open pages after installing or updating the extension.
