IDN Safe

IDN Safe is a powerful browser extension designed to protect users from phishing and spoofing attacks by blocking internationalized domain names (IDNs), also known as punycode domains. These domains can visually mimic legitimate sites due to their use of Unicode, making it easier for attackers to create fake websites that appear authentic depending on the font rendered.

With IDN Safe enabled, suspicious IDN domains are blocked by default to prevent accidental visits to probable fake sites. Users have the flexibility to temporarily allow specific domains or whitelist trusted ones permanently. This tool enhances online security by identifying and mitigating risks associated with maliciously spoofed domains. For more information and feature requests, visit the official GitHub repository.
