Browser information tool explained
Inspect this tab’s viewport, screen properties, language preferences and selected API availability. Refresh the snapshot after resizing or changing a browser setting, then copy or download it for troubleshooting.
A worked example
Viewport width describes the CSS layout space available to the page. It is different from the screen’s reported width and from physical panel resolution.
Before you use the result
Values are supplied by the browser and can be reduced, overridden or spoofed. An API being present does not prove permission, physical hardware or a successful operation. This does not request camera, microphone, location or notification access.
