What Is My Browser?

How to check your browser and version

1. Open this page in the browser you want to check. The name and version appear at the top straight away.
2. Read the update check. Green means the version is current or close to it; red means it is behind and missing security fixes.
3. Scroll through Supported web features to see which modern features work, for example if a website says your browser is not supported.
4. Press Copy browser and device info to paste everything into a support ticket.

What the results mean

• Browser and version come from the browser itself. Chrome, Edge and Opera on desktop and Android also share their exact build (such as 142.0.7444.60) through client hints; Safari and Firefox give the main version.
• Engine is the code that draws pages. Blink runs Chrome, Edge, Opera, Brave, Vivaldi and Samsung Internet; Gecko runs Firefox; WebKit runs Safari and every browser on iPhone and iPad, because Apple requires it there.
• The update check compares your version with the newest one, worked out from each browser's release schedule: Chrome and Firefox release a new main version about every four weeks, and Safari gets a new number each September. It allows for a version or two of lag, since updates roll out gradually.
• A cross in the feature list is not a fault. Some features exist only in some browsers (Web Bluetooth and WebUSB are Chromium-only), some need a newer version, and some are blocked by settings or by privacy modes.

How to update your browser

• Chrome: Menu (three dots) > Help > About Google Chrome. It downloads the update; press Relaunch.
• Microsoft Edge: Menu (three dots) > Help and feedback > About Microsoft Edge, then Restart.
• Firefox: Menu > Help > About Firefox. It checks and downloads; press Restart to update.
• Safari on a Mac: System Settings > General > Software Update. Safari updates come with macOS.
• Safari and every browser on iPhone or iPad: Settings > General > Software Update. The engine updates with iOS, even if you use Chrome there.
• Android browsers: Play Store > profile picture > Manage apps and device > Updates. Samsung Internet also updates from the Galaxy Store.

Leaving the browser open for weeks can hold an update back; closing and reopening it finishes the install.

Why your browser matters

The browser is the program you use most, and it runs code from every site you open. Each new version fixes security holes that attackers already know about, so an out-of-date browser is one of the easiest ways for malware to get in. Updates also bring speed and new features: a site that says "your browser is not supported" usually needs a newer version, not a different browser. For a deeper look at the device itself, see device info; for graphics support, the WebGL test.

Common problems and fixes

A website says my browser is not supported

Update the browser first (see above). If it is current, the site may check the name rather than features; try Chrome, Edge or Firefox, or turn off "request desktop site" on a phone.

Chrome says it is up to date but this page says it is not

A managed work computer can hold Chrome on an older version, or the update is downloaded but waiting for a restart. Relaunch the browser and check again. Ask your IT team if it stays behind.

The page shows the wrong browser name

Some browsers copy Chrome's identity (Brave, Arc, Opera GX and others), and privacy extensions can change it. The engine and feature list are still accurate.

Many features show a cross

Old versions, private or "lockdown" modes, and strict privacy settings switch features off. Update the browser and try a normal window.
