Extension Metadata

About this extension
Unicode Domain Guard protects you from potentially deceptive websites that use Unicode characters in their domain names. Some websites use characters that look like normal letters but are actually different, which can trick you into visiting phishing or spoofed sites.

When you visit such a domain, the extension displays a clear warning. You have the option to temporarily allow the site for 10 minutes, permanently allow trusted sites, or remove entries from your whitelist at any time.

This tool helps you stay safe online by making suspicious Unicode domains obvious and giving you full control over which sites are trusted.
