About this extension
Aegis Shield is a website blocker and browser security extension that helps you control which sites can be opened.

It works using a whitelist system. You choose the websites you allow, and all other sites are blocked automatically. This helps reduce distractions, limit unwanted access, and improve focus while browsing.

Aegis also includes optional protections to control actions inside websites, such as blocking downloads, uploads, and form submissions.

Key features include website blocking with whitelist control, blocking access to unwanted or distracting sites, controlling downloads, uploads, and form actions, preventing login and sensitive data submission, optional protections for paste and device access, and working completely locally in your browser with no tracking or external servers.

Modes include Strict Mode where only allowed websites can be opened, and Normal Mode where you can browse freely with protections enabled.

All settings are stored locally in your browser. Aegis does not collect personal data or track your activity.

Whether you want better focus, safer browsing, or controlled access to websites, Aegis provides a simple and reliable solution.
