Browser Info questions, fixes and result guides.
Practical answers for common browser info problems, confusing results and setup questions — with a direct path back to the live test.
How do I check my browser version and capabilities?
The Browser Information page combines browser-reported identity data with feature checks for APIs such as media devices, gamepads, storage and graphics. Exact version detail can be reduced by privacy features.
Why does my browser hide or reduce user-agent information?
Modern browsers intentionally reduce some user-agent detail to limit passive fingerprinting. Feature detection is usually more reliable than assuming capabilities from a long user-agent string.
What is the difference between API support and device availability?
An API can be supported by the browser even when the required hardware, permission or secure context is unavailable. For example, MediaDevices support does not guarantee a camera is connected or permitted.
Why can browser version detection be incomplete?
User-agent reduction and privacy features can limit exact version strings. The page prefers browser-reported brand data when available and uses conservative fallbacks.
Does Supported mean a browser feature will always work?
No. It means the API is present. Permissions, hardware availability and security context can still prevent a feature from working in a specific session.
How accurate is this browser info tool?
Browser detection is intentionally conservative and avoids aggressive fingerprinting.
What should I do if the browser info result looks wrong?
Update the browser, disable restrictive private modes for comparison and check permissions if MediaDevices or storage features are unavailable.
