Knowing your exact browser type, version, and technical specifications is essential for troubleshooting website issues, testing compatibility, and getting technical support. Our free “What is My Browser” tool instantly displays comprehensive information about your current browser, including the name, version number, user agent string, operating system, screen resolution, language settings, and cookie status. Whether you’re a website owner testing how your site appears across different browsers, a developer debugging compatibility issues, a user seeking tech support who needs to provide accurate browser details, or simply curious about your browser’s capabilities, this tool gives you all the information you need in seconds. No more guessing or manually searching through browser settings—everything is displayed clearly and ready to share or screenshot.

Your browser information reveals critical details about how you access and experience the web, with each element serving a specific purpose. The browser name and version (like Chrome 141 or Firefox 120) determine which web technologies and features are supported, as older versions may not display modern websites correctly or could have security vulnerabilities. The user agent string is a technical identifier that websites use to detect your browser and deliver optimised content, while your platform (Windows, Mac, Linux, etc.) affects how certain features and shortcuts work. Screen resolution and color depth information help developers ensure their sites look good on your display, language settings determine default content localisation, and cookie status shows whether you can use features that require stored data like shopping carts or login sessions. Understanding these details is particularly valuable when troubleshooting why a website isn’t working properly, as issues are often browser-specific or version-specific, and providing accurate browser information to support teams can dramatically speed up problem resolution.
