Developer comments

STOP-IT V2 is the successor to my original Stop-It extension. It has been rebuilt to comply with Chrome's Manifest V3 requirements while providing the same core protection.

The extension uses secure DNS filtering to block access to adult content, phishing websites, malware, and other harmful or illegal online content in real time.

This version is designed to be lightweight, privacy-focused, and requires no user data collection or tracking.
