What browser am I using?

Your browser, its version, your operating system and screen, read from this device. Copy the lot and paste it into a support ticket or bug report.

What support teams need from you

When a website works for the developer and not for you, the difference is usually the browser, its version, the operating system or the window size. Those four are at the top of this page. “Copy all for a ticket” puts them, with the full user agent, on your clipboard in a form you can paste into an email, a support chat or a bug tracker.

How the browser is detected

From the user agent, the text every browser sends with each request. It is reliable for the browser family and major version. It is deliberately vague about some details: Windows 11 reports as Windows 10, Macs report a frozen macOS version, and browsers built on Chromium that do not add their own name (Brave, for example) appear as Chrome.

What else belongs in a bug report

The page address, what you did, what you expected and what happened instead, plus a screenshot. The bug report generator lays that out and fills in this page’s details for you, and how to report a bug with a screenshot and console errors covers the console part.

Skip the copy and paste

With Layerdock, a reviewer clicks the element on the live site and types a comment. The screenshot, page, browser, OS and viewport are attached to the pin automatically, so nobody looks anything up. Try it on your own site, no account needed.

FAQs

Frequently asked questions

About this tool and the numbers it shows.

How do I find out which browser I am using?

This page shows it at the top: the browser name and its major version, read from the browser itself. You can also open the browser’s menu and choose About.

What is a user agent?

A user agent is a line of text the browser sends to every website, naming the browser, its version and the operating system. Developers use it to reproduce a problem in the same setup.

Why does it say Windows 10 or 11?

Windows 11 reports itself as Windows 10 in the user agent, so a web page cannot tell the two apart from that text alone.

Is the macOS version shown?

No. Browsers on a Mac report a fixed, old macOS version in the user agent for privacy, so the real version is not available to a web page. This page shows “macOS” only.

Does this page store or send my details?

No. The values are read by your browser and shown on the page. They are not sent anywhere or saved.
