What you're installing
SafeToOpen is a lightweight browser extension that checks the page you're on in real time and warns or blocks you before a phishing or scam site can do any harm. Unlike blocklists, it judges a site by how it looks and behaves, so it catches zero-day pages that have never been reported.
- Real-time, zero-day phishing and scam-site blocking
- Stops malicious downloads and known trackers
- Privacy-first — your browsing data is never collected or sold
- Free for personal use, with no account required
