How to interpret your results
The full browser test runs multiple checks in one place: HTML5 APIs, CSS features, WebGL graphics, WebRTC communication, storage health, notifications, clipboard access, and performance. If a panel fails, open the dedicated page to get deeper details and recommended fixes.
Guides
If something is blocked, follow a targeted fix guide for your browser.
FAQ
- Do these tests fingerprint me?
- No. The checks run locally in your browser and report capability status. We don’t attempt to uniquely identify your device.
- Why do results differ between browsers?
- Browsers ship different feature sets, permissions defaults, and privacy protections. Extensions and enterprise policies can also block APIs.
- What should I fix first?
- Start with browser updates and hardware acceleration (WebGL). Then confirm storage (cookies/IndexedDB) and WebRTC if video calls are affected.
